Been busy but here are progress some updates.
The side cargo area is all framed in, drop down doors frames fabricated and installed, stainless latches attached. The diamond plate skin did not arrive in time so had to run with out it for now. Before it first run in the mountains, stopped at Les Schwab Tire to have all the rubber valve stems replaced with metal, as they were slowly leaking.
The 7.4 moves the truck and the trailer loaded with the Can Am in mountains just fine. But the TH400 could sure use an extra gear between 2&3 along with an Overdrive. Even so it averaged 9mpg.
The LH side has room for all the camping stuff, chairs, BBQ, cooler fits in there as well.
RH side has a tool box built in, rack for the N2 tank, and room for all the pit boxes and spare parts.
Stopped outside of Sisters to camp. Hit several inches of snow going back over the pass the next morning - good thing for 4x4, it was a bit interesting...
It is a very comfortable and stable set up. So far no leaks, stayed warm overnight.
But do have a list of upgrades and fixes to do.
