I've got both an M105, and an M101. The M101 is very easy to modify so that the draw bar is the correct height to be pulled behind a regular sized vehicle and have the trailer be level. That's one thing that really bugs me bad.... When the trailer is doing a nose dive when it's pulled behind anything other than a big military truck. I've got mine setup to pull behind my Chevy Suburban. The lunette is really easy to flip upside down to make things line up better, but then in addition to that, I did away with the folding drawbar capability and welded some square tubing under the bed of the trailer to further level it out. I love the way it's turning out. I'm not done with it yet. Just been having to work on it here and there. I still don't have a plug on the light cord yet, or hooks on the safety chains. Just barely got the thing registered a couple days ago.
As you can see in my pics, the M105 is MUCH heavier duty and set up higher than the M101, and because it is so heavy duty, the draw bar would take a lot more work to atempt to make the trailer anywhere close to level when towed behind a regular vehicle. And as was mentioned, the trailer weighs 2,750 pounds empty. It is very difficult for me to muscle it around when trying to hook it up to one of my military trucks. I have to hope I can get it lined up just right with the truck so I don't have to move it.
When I went to buy these trailers I discovered the same thing. That the M105s almost always sell for less, and it didn't make any sense to me, since it is so much heavier duty of a trailer. But now that I know how much more useful the M101 is for everyday use, I totally understand. I bought my M105 for $150, and my M101 was $200.
