Interesting adaptation for the radio and one that makes sense because, what I've read is, official policy was to not mix cargo with personnel in the carrier. Or was that rule bent now and again?

Did you also use the Convenience Receptacle (yes folks, that's actually what it's called) located in the carrier's front bulkhead for the radio's power supply or did you fellas tap into the power elsewhere? I about spit out my coffee when I found out what it was called. Had me looking around for the cigarette lighter (just kidding).

I'll admit, I wasn't familiar with the M-578 VTR until I saw this -

Oh boy! That's really a peach of a vehicle. Small. Tracked. Armored. What's not to love? My bucket list just got longer, doggone it!

Fabulous input from M75. Keep it coming!

Cheers,
TJ

Are you sure that is a recovery vehicle? I was under the impression they were support vehicles for the 155 self propelled howitzers. They were used for changing out barrels. That boom is nowhere near strong enough for recovery operations.

Here's a visual quick overview of the four positions offered by the stock 10 o'clcock- 4 o'clcock retaining pin hole.

All forward and fully stowed. Weapon cannot be mounted to the gun mount in this position unless the mirror supports are removed. All other positions will allow for a mounted weapon.

And some detail photos of the gun mount. It got a bath and a good scrubbing, followed by a serious blow-dry with compressed air. Every nook and cranny. Not perfectly clean....yet.

I removed the gizmo from the M142 mount, bringing it into the proper configuration for this application and making the holes available for the retaining pin which is used to secure the gun mount to the arm.

In Armored Cav in middle 1970, Headquarters Troop Maint section had M578 to go along with M113’s. M88 for the M60 tanks. Pre-Abram and Bradley.

A little humor for my box of onboard hearing protection.

Is it recommended to wear ear protection while driving the gamma goat?

Not only recommended. It's mandatory. The volume of sound made by the Gama Goat is sufficient to damage human hearing after prolonged exposure. Conversation, even between crew members seated side by side is nearly impossible when it's under way. So loud, in fact, that the convenience panel in the carrier has a button that illuminates a light on the dash so that anyone seated in back can direct the driver to stop.

Sometimes it doesn't have to be prolonged exposure as I am sure you know, Some of the construction mentality long ago said I wasn't tough enough as I would have on hearing protection.My reply was very obvious standard reply.Glad you have it on

Yeah, my hearing is shot, compliments of the Taliban, but not entirely so. However, with age, I'm afraid what I have left certainly isn't improving. :roll:

So, tough or not tough, I have to practice some conservation.

The "VTR" reference for the M578 was for "Vehicle, Tracked, Recovery". For M113-family of vehicles, it was the TO&E recovery asset, one per line company and I believe one more at HHC, part of BN Maint section. I also believe the Armor Cav squadron next door also used M578, not M88, due to the relative light weight of the M551 Sheridan. The full-on armor units used the M88, which during my time were all still gassers, with that magnificent long blue flame shooting out of the rear when the throttle was let up on.
Artillery units used the M578s for recovery, as well as facilitating barrel changes on the gun tubes.
And regarding the power receptacle for the Goat radio fender mount, I don't know about how the power was plumbed to the mount; it was already in place, and I never thought to see how that part of the set-up was accomplished. It was just "there", and when we mounted the radio, it had power, so Hey, presto!
But then, experience also told me that a stubborn M151 would only start up after dipping a C-ration can into the gas tank to get some starting juice, removing the air cleaner hose, tossing the gas into the carburetor, jamming a hand over the carb opening, and having someone jam on the starter. I never saw that procedure in the TMs, but it sure seemed to start the truck up!

I had forgotten about the blue exhaust flames on the M88. Towing a dead M-60 tank at night, the blue flames were something. Those old MOGAS burners were pulling son of a guns. I recall also the front spade made an excellent place to sleep. Best remember where you are though. Heck of a thud if you rolled off.

I completely agree. Used to be nonchalant about this, but not anymore!
