Wanted Trailer ID help please

I've emailed the seller but need to know how heavy these are; he says one is smaller than the other but not sure which, nor how much they weigh.
thanks a bunch!

Those are M105s and very heavy. Rated offroad to haul a ton and a half. Probably double than on pavement. I would plan on using it with something lighter than at least a 3/4 ton truck. I have a M101 3/4 ton I fine very useful with my FJ62 and 100 series.

looks like the one one left is a M101A1 and the other is a M105a1. The left trailer hitch is not of a 105!

Either of those are too big to tow with a Land Cruiser.
