Nice build! I am planning to go the same route with the Dometic drawer fridge. Curious why not drive the 80 all the way down to South America? My wife drove our 80 from Guatemala to here and in the next few years, I'll be retiring (military) and plan to drive it down there. We have a vacation...
I have enjoyed my T4 here in SoCal so far. I have to admit I did not realize how big it would be in the bag! I'm still trying to find a better way to keep it in the rig.
It looks like the paint is not binding properly to me. I'd sand that down and then apply a primer. You would think the paint would bind but sometimes paint in finicky like that.
