Don't be too concerned with the size of the engine. There really isn't much of a selection.
They all get you from point A to point B. Some just take a little longer than others.
The overall condition of the RV is more important than the engine size.
^Overly broad statement and shows you aren't well read on what the OP is asking.
Like carringb said, 360 has to be an OLD Dodge or even older Ford assuming they put 360 fords in RVs back in the day.
460 Ford, good motor, but I wouldn't even consider a carburetor version.
Based on the engine selections presented and the OPs question, I'm surmising budget well under $10k and not a gear head or shade tree mechanic.
With that I'd advise away from RVs older than 20 years and certainly stay away from ones parked out on the tundra.
Any older vehicle can be fairly reliable or a basket case (not just the engine/drivetrain, but brakes, electrical etc.
RVs are also typically much more expensive in AK for what you get. I actually sold our camper, trailers, atv in AK before we moved back after living there for a bit and made a healthy profit. All were bought/brought from the L48 with us when we moved up.
With flights and fuel cheap, I would consider lining up a bunch of good candidates down here, fly down with $$. Find the right one and drive back. End of the day it "may" cost similar as buying up north but will be a much greater selection.
Caveat being if truly looking at old low buck RVs I wouldn't want to drive an unknown one 2000mi back up there before going through it and some good shakedown miles.
Engine wise, I would only consider 6.0 Chevy or V10 Ford unless I was really good with a wrench.
