So I looked thru the rental links...
Seems the host(s) are the same for both vehicles and are quite possibly based in AK and/or familiar enough with driving off-highway in AK (per description).
Interesting the rigs that they have chosen for their rental business/sideline. Maybe not the first rig, which might have been a family truckster, but likely the second one which is much like the first.
I note they advertise these units offered with, "no road restrictions":
- older trucks (18,19 yo)
- stock or mostly stock. (Despite the huge industry for mods)
- 6.0 diesel (despite the poor reputation - tho they may have been modified/fixed)
- Palomino Camper (despite, AFAIK, not having the best rep for build quality/durability)
- soft side pop up (despite AK bear population)
At least some of the above may be at odds with what one might usually read.
Question for the curious, which rig came first and how did that play into the choice for the second rig. Was the F250 the first, modded for fun and specific needs. The F350 the second, mods deemed not necessary ? Or vice versa ?
This is was my point in renting the stock truck and camper. One might be surprised how well it does for what "most people" might do (at least the renting public).
What a vehicle doesn't/can't do might be addressed with mods but I would never think folks spend money on mods only because said mods "work". Some folks just like spending money, or like building up cars and trucks. Some is for looks, some for performance, some for reasons that didn't quite pan out.
Sure mods like larger fuel tanks might "work" in that range is extended. Whether that is needed or is good value is a whole 'nother thing.
And some mods beget other mods. Want larger tires ? well you might need new rims, and a lift, which leads to new and longer shocks etc.
Anyway, good move on the truck camper rental if that's where you want to end up. Hope it's money well spent.
Btw, devil incarnate or not, the 6.0 diesel will prob give better fuel economy than the gas versions would have, which will help with range, but prob not enough to make up the current fuel price difference. But it might scratch the diesel itch.
