I had an email question. "What kind of bolts are you using?"
We are using aircraft bolts anywhere there is a through hole that needs to be bolted together with a nut. You can see that on the front of the chassis where the jack hooks bolt on. When we have to bolt directly into the aluminum, we are using coarse threaded bolts. They are not aircraft bolts, but USA made, grade 8 bolts--where possible. We can't get a hold of AN (military/aircraft) coarse threaded bolts, or we would use them. We try to use "Unbrako" or other high quality socket head cap screws or taper head cap screws where possible. The large surface area under the head of a taper head cap screw really helps to hold the parts together.
