Just read through this posting over on Pirate4x4.com and was intrigued by the concept:
i don't think the 55" tires would be ideal, but the smaller tires with only one rear axle could be a starting point...thoughts?
I'm
turning a deuce into a motorhome right now.
Lots of info here. Let me know if you have any more specific questions.
Cons:
Too big for most trails.
Need ear protection.
Really not all that much bigger than a fullsize pickup truck.
i've hear they are loud as all get out...is it just exhaust noise or are the engines that loud? could you muffle the intake and exhaust better?
The noise pretty much comes from everywhere. There is no muffler for the exhaust and the firewall is straight sheetmetal. I'm sure with some time and energy you can quiet them down to a more manageable level.
Yes, they're noisy. Deuces were not originally equipped with any sort of mufflers.
Adding a muffler is pretty easy though, and that alone makes a pretty big difference. Lots of other things you can do to decrease the noise in the cab even more.
As for anyone possible buying one, the ARMY did a modification to the IP and took away the multi-fuel aspect on the later ones to only burn JP-8(diesel) since there isn't anything that really burns MOGAS in the inventory any longer. Going to one common fuel. There is a sticker on the IP that states so.
That's not exactly right. What they have done on a lot of vehicles is to bypass the fuel density compensator, which injects more/less fuel depending on how combustible it is. The fuel-density compensator has been bypassed on mah deuce, and I can tell you from first-hand experience that it still runs just fine on everything from diesel to gasoline to used motor oil.

How long from cab to end of frame I wonder? Would they allow a custom choice of length?
A standard-length deuce (without a winch) is about 26ft long. Most of the bobbed deuces are custom-built, so I'm sure you can have one made to whatever length you want. There's even a LWB version of the deuce called the M36 that had something like a 16ft bed on it. You could also bob a deuce and leave it full-length, but it's going to have a ****ty breakover angle unless you get some 46"+ tires and/or move/get rid of all the under-cab storage, spare tire, fuel tanks, etc.
if you read through the posting on pirate4x4.com someone says they averaged 10-12 mpg with stock tires and anticipated better mpg with larger tires (which this has) and the elimination of the second rear axle...so conservatively a gain of 1-2 mpg?
Probably not ever going to get much better than 12mpg in a multifuel deuce.
oh, and stock top speed is 50 mph, but would be faster with one less axle...
Not really, top-speed is limited by RPM's more than anything else.
Some of the later trucks had Cat's (3116 IIRC) and Allison automatics. I have even seen one with a Cat, Allison & CTIS up for auction, but it sold for quite a bit -- I think it sold for $26,000 (again IIRC).
The M35A3 trucks all have cat engines, allison transmissions, and CTIS. You can pick one of those up for $8000-15,000. Got mixed feelings about those though. No multifuel, lower top-speed than the M35A2's, the CTIS is notoriously unreliable, and well, they're ***-ugly.
Just FYI the best mpg one could hope for out of one of these is 8mpg.
I was routinely getting close to 10mpg in my (empty) M109. Expect to get somewhere around 6mpg when it's finished, and that will be with a 5-ton LDS multifuel engine, pulling about 22,000-24,000lbs. That's on par with motorhomes of similar size/weight and remember, with these vehicles it's more about the miles-per-dollar than the miles-per-gallon.
You might use a little caution when shopping for a Bobbed Deuce, specifically to legality of registration and street driving. Many are 'off road use only,' and have no way to register them.
Those that have gone to the trouble to get title and registration usually mention it in the advertisement.
That's just to limit the builder's liability. Has nothing to do with being able to register them.
