But don't try to return it to The Well Known Marine store if it's the wrong size, or dies before the warranty is up. Just wrap it up, pay the return postage to camping world, wait a week or 10 days for the replacement, oh, and probably pay for shipping again. As stated in the next post, West will match prices, including the shipping cost. Just bring a current ad or proof of pricing.
