Is the 1102 pretty much the same dimensions as the M101? Because I know the M101 really is not big enough to be used as much of a camper. But the M105 has plenty of room in it to at least put two cots side by side or something.
Just a note about their size difference. The other day I decided I was going to go buy a four wheeler, or quad. I drive a Chevy suburban, so I needed to take one of my trailers to get it. I wanted to take the M101, but it had a friends dining room table in it, so I decided to take the M105 instead. Boy am I glad I did! When I got home I discovered that there was no way the quad would have fit between the wheel wells in the M101. I was surprised how much smaller the M101 was inside compared to the M105.
But yeah, while the M105 is pretty big and heavy if you intend to pull it with your regular vehicle, I think it is a much better choice for pulling behind your M35. And you can usually get them cheaper because they are not in such high demand as the smaller lighter ones.
