Just a little update, after camping I found water would leak in through the topper and drip on my tailgate. Didn’t really want to pay money for an already assembled awning and the way they mount I would have to jimmy something up anyway. So I made my own awning with some conduit.
Secondly, after driving the truck and taking it to the mechanic, it’s the transmission that’s pooping the bed, just slipping gears, so that sucks...
