I have both an M105A1 and a M101A1
the M105A1 is a beast, frakken heavy and I only use it behind my Deuce.
The M101A1 is a lot more practical, simply due to its lighter weight.
I tow my M101A1 behind my F150 and it goes fine.
They are rated for 3/4 ton across country and 1.5 tons on the road, the
M105 is 1.5 tons across country and 3 tons on the road.
Yes, you will need a high pintle.
Here is my M105A1
and my M101A1
Here is the M101A1 just sitting on a ball hitch on my F150 when I first got it.
I had to put a good reese hitch on the truck and get a pintle and high mount
The M101A1 is still a big trailer and not something I would want to haul behind a Jeep.
I got mine for $301 and then picked up a cover. I just need a bow kit for it.
I'm going to repaint it next spring and make some mods to it.
I have the old wheel bolt pattern/rims/tires. You can find them with the same bolt/wheel
pattern as the M1009s with modern radials.
