, we got a Scamp13 with the 54" bed and front bench/bunk beds.
Because we were told that you are supposed to travel with the rear table/bed in the down/bed configuration, we got a lightweight folding table from Walmart to use with the front bench for rest-area lunch stops. It is a little better and sturdier than the old TV tray idea, but still lightweight and fairly compact when folded up. (I think that Camping World has something similar.)
Since we are middle-age+, we sometimes get up during the night for a restroom break (the wider bed makes it easier to crawl over/around). If one or the other gets a bit congested and snores a little, the additional width provides for at least a little more separation ... Or there is the option of the seat of the front couch. (We wanted the front bunks for occasionally taking our grandkids along on outings anyway.)
The first night that we spent in the trailer, the temperature dropped below 30 degrees and, although we were toasty warm, our sleeping bags are/were the old rectangular variety and not the tapered mummy bags. Even with the wider bed, there was some overlap of sleeping bag edges.
As mentioned in another thread, our biggest disappointment with the 54" bed is that Scamp
decided to use a smaller 32" table and a 20" filler board to support the wider bed. That will/would seem to make it a bit cramped for 4 adults (or 2 adults and 2 grand kids) to have an indoor meal at that smaller table in inclement weather .... or for 4 people to play cards (or board games?) in the evening. (I will probably need to come up with another table/filler-board option soon.)
Good luck with whatever you decide.
