During my time in the Signal Corp, we had our AN/GRC-142 shelters mounted on the '715. Of course, we did not mount them ourselves, we received the trucks and commo gear ready to roll.
When my truck is out of the restoration mode, I'll be mounting my complete AN/GRC-142 on the back. My questions revolve around the '715 "quirks" booklet on the subject of shelters.
This is a copy of what is in the "quirks" booklet;
M715 COMMO GEAR GIVING YOU INSTALLATION AGGRAVATION?
You may’ve already found out the hard way that commo installation kits for your M37 (G741 series) 3/4-ton cargo truck aren’t right for the new M715 1-1/4-ton job. Hang in there. With few exceptions, help is coming. A revised SB 11-131 is on the way with listings for the M7l5 and other new vehicles.
No kit is planned for the Angry-46, because the Standard B set is scheduled to be replaced by the AN/GRC-142. Which means you improvise, should you lose your M37 to an M715. It’s a matter of lengthening tie-downs and adding a few 2 x 4’s around the Angry-46 shelter. For the present the Angry-142 and the AN/GRC-122 radio teletypewriter sets will be installed n the M715 in the S-318 Shelter, which was designed for the M37 3/4-ton. Which means you’ve got to improvise to install the shelter, just like with the Angry-46.
Well, I certainly do not remember using or seeing 2x4's around our shelters. Measuring the shelter and the bed of the truck says it will fit nice. The shelter will be a bit narrow between the wheel wells, unlike the M37, but so what? Also, the bed is longer then the shelter but again, so what? It fits almost perfectly side rail to side rail. The tie downs will hold it in place.
Any mil-rad guys out there who remember what they are talking about with the shelter mounting needed to be "improvised"?
