I also agree with Whazoo. I have had my Apex 8 since 2011 and Bob and Outfitter have bent over backwards to answer my question. You get a more prompt response if you call, however. They have made repairs on my camper at no cost to me several times. Please don't be negative about them. They have outstanding customer service!! Also, any owners manuals that is not associated with the structure Outfitter gives the customer the factory manuals at purchase and the factory warranties apply. Do you have the factory manuals? Glad to have another Outfitter owner in the forum...Terry
