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 2018 and Fiscal 2017 are 52-week years.
New Accounting Pronouncements [Policy Text Block]	Recently Adopted Accounting Pronouncements 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. We adopted this ASU in the interim quarterly reporting period ended November 25, 2017. Amendments requiring recognition of excess tax benefits and tax deficiencies in the statement of income and comprehensive income resulted in $0.6 million of excess tax benefits recorded as a reduction of income tax expense upon adoption for the three months ended November 25, 2017. The reduction in income tax expense also reduced the effective tax rate by 2.2% and added $0.02 to income per share for the quarter ended November 25, 2017. Amendments related to the presentation of excess tax benefits and employee taxes paid when an employer withholds shares to meet the minimum statutory withholding requirement required no change to the statement of cash flows. There were no material impacts on the consolidated financial statements of the Company which adopted a policy of accounting for forfeitures when they occur. In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330), which requires inventory measured using any method other than 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 is effective prospectively for fiscal years beginning after December 15, 2016 (our Fiscal 2018), including interim periods within those annual reporting periods. We adopted this ASU on August 27, 2017, and there was no material impact on our consolidated financial statements. 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 have performed an evaluation that included 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. Based on our preliminary review, we do not expect adoption to have a material impact on our consolidated financial statements but further work to substantiate this preliminary conclusion is underway. We will determine the transition method to apply and the implications of using either the full retrospective or modified retrospective approach after this additional work is concluded. 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 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 August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815), which improves the financial reporting of hedging relationships to better portray the economic results of an entity's risk management activities in its financial statements. ASU 2017-12 is effective for annual reporting periods 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 February 2018, the FASB issued ASU 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220), which allows for a reclassification of stranded tax effects from the Tax Cuts and Job Act from accumulated other comprehensive income to retained earnings. This ASU is effective for fiscal years beginning after December 15, 2018 (our Fiscal 2020). 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. Reporting Segments We have two reporting segments: (1) Motorized products and services and (2) Towable products and services. We aggregate two operating segments into the Towable reporting segment based upon their similar products, customers, distribution methods, production processes and economic characteristics. We adopted a new corporate allocation policy in the first quarter of Fiscal 2018 that identifies shared costs and allocates them to the operating segments. The cost drivers selected as the basis for allocation are the most appropriate drivers for the type of cost being allocated. All corporate expenses are allocated to the operating segments. Previous to the first quarter of Fiscal 2018, costs were not allocated and were borne by the segment in which the costs originated. See Note 3: Business Segments.
Subsequent Events [Policy Text Block]	Subsequent Event On March 14, 2018 our Board of Directors declared a cash dividend of $0.10 per share as further described in Note 11.
