OK, I think I looked at all the options, and for the money went with another 78" ATC Ocelot shell. I'm thinking about eventually building it into a complete camper with the side dinette. ATC is going to offset the door 6" to the driver side which will make more room for the side dinette.
I'm going all electric no propane except a portable Colman propane stove and a Mr. Heater buddy. Thinking about putting in the TruckFridge T49AC/DC fridge, 10 gal freshwater with pump and sink. I saved the 75AHr battery, 100W solar panels, and solar controller from the wrecked camper. I'm moving the fridge, water and battery all to the front of the camper and mounting them as low as possible for better weight distribution.
ATC said it should be ready in about 8 weeks so I guess I will be making a trip to Reno NV in March and shell camping in the desert Southwest on the way back home via Death Valley and Big Bend NP.
