How are these campers usually attached to the trailer frame?
I took notes while reading the thrifty alturnative thread, but all I see is glue? I'm having trouble imagining th at glue would hold the 2x4 frame of my camper to the metal frame of the trailer.
We have been talking about several different options.
Bolts with strong metal plates at each end seems like way too much, and a good bit of extra weight too.
Someone suggested zip ties.

plastic breaks down over time.
We are leaning towards metal cables.

Each would have a weight capacity of over 800 lbs . Hopefully our entire camper, including the trailer, won't weigh much more than that.
