We ordered a 35ROK but we did consider the DEK. We looked at the Sierra version of it at a dealer in Lancaster Ohio. It's pretty unique with that big porch dropping down in the rear. We thought how cool that would be backed up to a lake or river and dropping that thing right over the water! It has a sliding glass door going out to the DEK. We decided against it because when its up the inside is rather dark because it blocks the glass completely. As long as the RV is, it is even longer with that thing down and we would be limited on campgrounds because we wouldn't be able to put it down in a lot of sites. It's about 55' long with it down. Other than that though its pretty cool. I lifted it up and down, not too bad but not sure if the DW could handle it. The dealer wanted $41500 for it in Lancaster if you are still interested, not too bad but $2000 more than I paid for my ROK.
