I just purchased 255DRL4 Memorial day weekend. We've only taken it on one weekend trip so far. Love all the features as well as the layout. I've already had two minor problems though. One is the bed does not go up and down and they're scheduled to look at it next week. The second problem was with the breakaway switch. It seems the wired leading to the junction box from the switch were too short so when I backed it up at home on a short right turn, they pulled out of the switch box.
I'm now waiting to hear back from Forest River for a reimbursement for the new one I installed. It would have took to long to take to the dealer and we are going camping for the Fourth of July weekend. We'll see how she does this weekend. By the way there is one other thing. When you're in bed, the light from the light switches are way too bright. We have to cover them up in order to sleep.
