Sam, Allan, and those others who assisted in my quest for accurate dimensions, thank you.
I was in the enviable position of being far from home next to a short-deck equipment trailer that would be great for hauling the V100 around in tight quarters,
and having an M915 tractor to haul it home with!
IF it would fit behind my M931A2 without hitting the back tires when I turn.
I can haul my M128 around just fine with the 931, if I flip the landing gear feet back and strap them vertically to the legs.
This trailer looked close, but maybe too close. I had some basic measurements stored in my head, but not quite enough to make a good decision, and needed some M931A2-specific measurements (or A1).
Sarge was, of course, about 100 yards from my truck, since he is my neighbour, but he has no phone! Everyone else was at work.
But by measuring other trailers on the lot, the 915 and some civvy tractors, I finally figured out that no amount of wishful thinking was going to change the fact that I just can't haul that short-necked trailer behind my fat-arsed truck. Even Santa Claus couldn't make that work.
So I left it there and came on home with an empty 5th wheel....
(And yes, I could move the 5th wheel back, or put my truck on 11.00s, or buy myself an M915, or re-neck the trailer, but none of those are viable options for me to haul just one trailer around, so...)
Cheers
