It checks a lot of you boxes:
1. It's pre DEF so it will burn high sulfur fuel
2. it has torsion free subframe. I've posted a link to my build thread so you can see how it works
3. You can stand inside the Hallmark Camper it's 79" floor to ceiling with the top up. You can also sleep in the bed. Its 80" long.
4. I am asking $120,000 for it so it is in your budget.
5. Fuso is simple and uncomplicated. It has been maintaind by Portland Mitsubishi Fuso while we have had it. We replaced the usual things that break on this vintage of Fuso's- Transmission, clutch and transfer case replaced with factory new unit. Alternator replaced and ERG replaced. It has fresh oil change and coolant flush and replaced. It comes with belt and hoses so you have them on board just in case.
We have taken it to Alaska and it did great. The ATW suspension and upgraded seats make a huge difference on long trips. It's very capable off road. We did some stream crossings to exit Wrangell-St Elias NP when a suprise storm washed out the road. We got out and they closed the road behind us and the Rangers said it probably wouldn't be open again for a month or so.
It's ready for another adventure! PM me if interested.
