First weekend out with the new bunks worked great. The 10 year old loved having a loft to sleep in. The baby slept great (her mattress is made of sponge from Pelican Cases). The wife loved our newly found space on the extended counter where the 10 yr olds bed used to be.
Also put shelving in the closet so there's even more room to tuck way stuff.
from the threaded rod coming from the roof. There is butyl tape sandwiched between two washers on either side of the fiberglass.
The aluminum c-channel braces on the roof provide enough support that there is virtually no movement when the bed is being used.
So far so good. The important thing is now I can keep the trailer and not upgrade to a bigger setup to accommodate the kids. The other option was to remove the extended counter and toilet and put in front bunk beds..... We hated that idea of course (we love the counter and flush toilet)
Total cost was $200 ish in wood and fixtures.
We love our new setup.
