Don't underestimate the capabilities of old IH iron. I've had my college truck, a 1967 Scout 800, since 1973. The Dana 44 rear is solid and the Dana 27 front is "good enough". Ditto the Dana/Spicer 18 twin-stick transfer case--solid piece of equipment which served well in larger vehicles of that vintage. Even the old Borg-Warner 3-speed, featuring unsynchronized 1st gear, is solid.
And those IH engines! Class A tractor, medium duty truck, and dumptruck power plants. IH put the 304 in many a medium duty truck and the Scout II models from 1972-1980 offered a 392. Ever willing to use off-the-shelf components, IH used half of a 304 as the 152 4-cylinder in the early to mid-1960s and the 392 trimmed out as the 196 4-cylinder. Each 4-banger kept its orientation as a slant 4 in order that the bellhousings would match up readily as either the V-8 or the slant 4. You'd think the halved engines would be very light, but you'd be wrong--I also have a 1965 Scout 80 in the stable and she sports a 152. The engine block weighs 525 lbs, about 25 lbs more than a full smallblock Chevy 350 V-8 weighs. My 1967 Model 800 sports a 266 cu inch V-8 which also came from the full-size pickup, Travelall, and medium duty truck parts bins. Its block weighs just over 700 lbs.
As best I recall, Four-Wheel had a line of pop-up campers available in Scout IIs, Travelers, and K-5 Blazers. Believe they were sold through the IH and Chevy dealership networks a-la the early Napco and Marmon -Herrington 4WD modifications to Chevy/GMC and Ford pickups, respectively.
Maybe the old Scout isn't for everybody, but she rings a bell with me.
