Many salesmen do not realize there are two queens, RV queen and regular queen. We had a RV queen in our first travel trailer, replaced it with full size queen that hung over the end of the bed support and told the buyers when we sold exactly what we did and not to sit on end that is not supported. I know we could have fixed it by adding support but not a problem. If you find a trailer with the short version but otherwise like the trailer, you might be able to change mattress and add support if needed...
