Light, at 800 lbs. empty
Aerodynamic, flat bed, "easy on gas"
Great ground clearance, with massive 37X12.5 tires with run flat inserts.
Versatile, with a 2,360 lb. payload.
Place your rain/dust proof containers on the bed and fill them with gas, water, camping supplies, tools, etc. etc. and then use ratcheting straps to tie them to the bed, or if you want them permanent, just bolt the containers to the bed.
This then frees up your Wrangler from all the stuff that is inside, outside, on top etc. for other things, like your four legged best friend. How many times have you had to leave things behind because there was just not enough room.
These trailers are cheap at about $1,000. http://redding.craigslist.org/for/4606962585.html
#1, the majority of these trailers are aluminum, they don't rust.
#2, you can find them all over the East Coast for comparable prices, if not for less.
#3, most being auctioned off are less than ten years old.
The M116a3's are all steel.
The M1101 and M1102 have aluminum beds and weigh 1460 lbs. empty.
I have one M1101 and three M116a3's.
The M1101 trailers out here are mostly under 10 years old, as you said, but most of the M116a3's are a little older.
M1101 = 1460 lbs. empty
M116a3= 800 lbs. empty.
This is my dedicated Jeep trailer. Not as cool as the military's, but works great for my needs. I store doors etc inside and still tons of space for gear. Weighs less than 600 (I'm guessing here, but it's very light).
I don't always drive a Jeep, but when I do it's dirty! Rear Seat Reversal
