Accounting Policies [Abstract]
Fiscal Period [Policy Text Block]	Fiscal Period We follow a 52-/53-week fiscal year, ending the last Saturday in August. Both Fiscal 2017 and Fiscal 2016 are 52-week years.
Goodwill and Indefinite-Lived Intangible Assets [Policy Text Block]	Goodwill and Indefinite-Lived Intangible Asset Goodwill resulted primarily from the Grand Design business combination and represents the excess of the purchase price over the fair value of tangible assets and identifiable intangible assets and liabilities assumed. Annually in the fourth quarter, or if conditions indicate an interim review is necessary, we assess qualitative factors to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount and if it is necessary to perform the quantitative two-step goodwill impairment test. If we perform the quantitative test, we compare the carrying value of the reporting unit to an estimate of the reporting unit’s fair value to identify potential impairment. The estimate of the reporting unit’s fair value is determined by weighting a discounted cash flow model and a market-related model using current industry information that involve significant unobservable inputs (Level 3 inputs). In determining the estimated future cash flow, we consider and apply certain estimates and judgments, including current and projected future levels of income based on management’s plans, business trends, prospects and market and economic conditions and market-participant considerations. If the estimated fair value of the reporting unit is less than the carrying value, a second step is performed to determine the amount of the potential goodwill impairment. If impaired, goodwill is written down to its estimated implied fair value. As of May 27, 2017, we had an indefinite-lived intangible asset for the trade name of $148.0 million, from the Grand Design acquisition. Annually in the fourth quarter, or if conditions indicate an interim review is necessary, we assess qualitative factors to determine if it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount. If we perform a quantitative test, projections regarding estimated discounted future cash flows and other factors are made to determine if impairment has occurred. These assumptions require significant judgment and actual results may differ from assumed and estimated amounts. If we conclude that there has been impairment, we will write down the carrying value of the asset to its fair value.
Other Intangible and Long-Lived Assets [Policy Text Block]	Other Intangible and Long-Lived Assets Long-lived assets, which include property, plant and equipment, and definite-lived intangible assets, primarily the dealer network, are assessed for impairment whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. The impairment testing involves comparing the carrying amount of the asset to the forecasted undiscounted future cash flows generated by that asset. These assumptions require significant judgment and actual results may differ from assumed and estimated amounts. In the event the carrying amount of the asset exceeds the undiscounted future cash flows generated by that asset and the carrying amount is not considered recoverable, an impairment exists. An impairment loss is measured as the excess of the asset’s carrying amount over its fair value and is recognized in the statement of income in the period that the impairment occurs. The dealer network is amortized over its estimated useful life of 12 years. The reasonableness of the useful lives of this asset and other long-lived assets is regularly evaluated. There was no impairment loss for the period ended May 27, 2017 for goodwill, indefinite- or definite-lived intangible assets, or long-lived assets.
Debt Issuance Costs [Policy Text Block]	Debt Issuance Costs We amortize debt issuance costs on a straight-line basis (which is not materially different from an effective interest method) over the term of the associated debt agreement. If early principal payments are made on the Term Loan, a proportional portion of the unamortized issuance costs will be expensed. We incurred $0 and $0.8 million of costs in the three months and the nine months ended May 27, 2017, respectively, related to our revolving credit agreement that are being amortized on a straight-line basis over the five year term of the agreement. We incurred $0 and $10.2 million of costs in the three months and the nine months ended May 27, 2017, respectively, related to the Term Loan that are being amortized on a straight-line basis over the seven year term of the agreement.
Derivatives [Policy Text Block]	Derivative Instruments We use derivative instruments to hedge our floating interest rate exposure. Derivative instruments are accounted for at fair value in accordance with ASC Topic 815, Derivatives and Hedging. We have designated these derivatives as cash flow hedges for accounting purposes. Changes in fair value, for the effective portion of qualifying hedges, are recorded in OCI. We review the effectiveness of our hedging instruments on a quarterly basis, recognize current period hedge ineffectiveness immediately in earnings, and discontinue hedge accounting for any hedge that we no longer consider to be highly effective.
New Accounting Pronouncements [Policy Text Block]	Recently Adopted Accounting Pronouncements In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Topic 835), which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. We adopted the standard during the first quarter of Fiscal 2017 and, accordingly, have presented unamortized debt issuance costs as a direct reduction allocated between Current maturities of long-term debt and Long-term debt, less current maturities on the Consolidated Balance Sheet as of May 27, 2017. In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805), to simplify the accounting for measurement-period adjustments in a business combination. Under the new standard, an acquirer must recognize adjustments to provisional amounts in a business combination in the reporting period in which the adjustment amounts are determined, rather than retrospectively adjusting the provisional amounts recognized at the acquisition date with a corresponding adjustment to goodwill as under current guidance. ASU 2015-16 is effective prospectively for fiscal years, and the interim periods within those years, beginning after December 15, 2015 (our Fiscal 2017). We adopted this standard on August 28, 2016 and have accounted for all adjustments to provisional amounts in accordance with this guidance. New Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which establishes a comprehensive new model for the recognition of revenue from contracts with customers. This model is based on the core principle that revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Entities have the option of using either retrospective transition or a modified approach in applying the new standard. The standard is effective for fiscal years, and the interim periods within those years, beginning after December 15, 2017 (our Fiscal 2019). We are currently evaluating the approach we will use to apply the new standard and the impact adopting this ASU will have on our consolidated financial statements. This evaluation will include a review of representative contracts with key customers and the performance obligations contained therein, as well as a review of our commercial terms and practices across each of our segments. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330), which requires inventory measured using any method other than last-in, first-out (“LIFO”) or the retail inventory method to be subsequently measured at the lower of cost or net realizable value, rather than at the lower of cost or market. Under this ASU, subsequent measurement of inventory using the LIFO and retail inventory method is unchanged. ASU 2015-11 will become effective prospectively for fiscal years beginning after December 15, 2016 (our Fiscal 2018). We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and do not expect adoption to have a material impact. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires an entity to recognize both assets and liabilities arising from financing and operating leases, along with additional qualitative and quantitative disclosures. The new standard is effective retrospectively or on a modified retrospective basis for fiscal years beginning after December 15, 2018 (our Fiscal 2020), including interim periods within those annual reporting periods. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718), which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for the related income taxes, forfeitures, statutory tax withholding requirements and classification in the statement of cash flows. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016 (our Fiscal 2018), including interim periods within those annual reporting periods. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and do not expect adoption to have a material impact. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments (Topic 230), which provides guidance for eight specific cash flow issues with the objective of reducing the existing diversity in practice. ASU 2016-15 is effective retrospectively for annual reporting periods beginning after December 15, 2017 (our Fiscal 2019), including interim periods within those annual reporting periods. Early adoption is permitted. We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and do not expect adoption to have a material impact. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (Topic 350), which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment change. ASU 2017-04 is effective prospectively for fiscal years, and the interim periods within those years, beginning after December 15, 2019 (our Fiscal 2021). We are currently evaluating the impact of adopting this ASU on our consolidated financial statements and do not expect adoption to have a material impact.
Subsequent Events [Policy Text Block]	Subsequent Events In preparing the accompanying condensed consolidated financial statements, we evaluated the period from May 28, 2017 through the date the financial statements were issued, for material subsequent events requiring recognition or disclosure. No such events were identified for this period.
