The outside rail of the bunk is bowed. Its been bowed for a long time, and I cant be sure if it didnt came like that or that the frame may be broken. We dont use the upper bunk as a bed because with only the one Crusket at home we dont need to and we discovered early on, as you would well know, it gets stuffy up there in the penthouse.
Ive had it in the back of my mind for a long time to one day pull it apart and check it. For about the 35th time Ive trashed the inside of the van doing some mods and adjustments so it was as good a time as any to rip the bunk apart.
I have 5 grand kids, number 6 on back order and plenty of chitter chatter of it not stopping there. My eldest has a tent, and my daughters family tends to get cabins, or flop in our annex. Despite camouflaging the upper bunk as sundry storage, its only a matter of time before one of the the kids (or parents) works out that there is a ladder hanging on the bathrom wall, and that "storage area" is actually a fully functioning bed that theyll likely want to stay in, inside the relative luxury of the van
Bowed you say? What, Jayco's internal ply isn't up to the job? Oh the surprise!!
Fair enough... here's an idea... beef up the ventilation on the top deck and shift the Crusket up there. Then redesign the bottom bunk with an array of fridges, appliances such that the "bed" becomes a virtual serving bar for beverages and ales via the window for the outside world. With you unparalleled nouse around cabinetry, I can see some kind of flash serving table on a draw slide. At night, push it back in, voila! All secure.
That'll stop the suckers wanting to free load off your bed.
