That M989 looks kind of like what I have been scheming to do. I am thinking about buying two M105's, and taking the beds off, cutting the tongue off of one, and attaching it to the back of the other, and putting a deuce bed on it and then put 14.00 R20 tires or bigger on it and make it ride level. I am a good welder/fabricator, so doing something like that would be a piece of cake for me, and I'm not at all worried about how much it can actually haul. I mostly just want it for the looks. To have a big proportionally sized trailer behind such a big truck. Not concerned with functionality or the issue of it being such a pain to load stuff into a trailer that is so high off the ground or anything like that. Most likely wouldn't ever be hauling anything with it anyway.
Since it would just be for show, I would prefer to have an actual, produced trailer, but I think I could pull off a specially constructed one all well. Making the brakes work on both axles would be quite easy as well. But again, not entirely important since it's not going to be hauling much of anything ever anyway. ha ha
