We purchased a 2013 Elevation 5th Wheel. After having problems with the big living room slide...the kitchen slide and living room slide were hitting each other causing the LR slide not to go in all the way.....we were told by the camper place that there is no way to crank those slides in if motor doesn't work. It has to be manually pushed in. Think about it..how do we push the bedroom one is when it 10 feet off the ground and the big LR slide will take 20 men to push it in....not happy about that.
Then we were told that Elevation does not make a ladder for the bunk beds...How in the world do you get on the top....take a running start and jump hoping to reach the top?
When we purchased our 1st trailer SOB there was no ladder to get in the bunks. This trailer doesn't have either, but now the girls don't need one. You may want to surf RV parts on the web and see if you can find something, or just build something yourself out of 2x4 and 2 x2s.
On a side note I know when we looked at TH's some had ladders integrated right into the wall.
