Wrangler JK and the M1101 Trailer

I picked up a M1101 trailer from GovPlanet last spring. My original intent was to mod it into an off road camper but I have had some experience with it that is making me change my mind. I thought maybe it would be helpful if i passed it on.

First of all, the trailer cost me $925 plus fees last Spring from GovPlanet. It is a 2010 Silver Eagle that was issued to the Kansas Army National Guard and i was able to pick it up at their base in Topeka. The fees included the 10% buyer's premium paid to GovPlanet and then Kansas and Topeka sales tax as well as a fee to receive an SF (Standard Form) 97 which is what the government issues in lieu of a title. That allowed me to apply for and receive a title from my home State as well as register and license the trailer. So, out the door was just over $1,100.00. I had previously bought a wiring adapter to allow me to hook up the trailers 24v wiring to my four pin 12 v receptacle on my 2014 Jeep Wrangler JK. The trailer is equipped with multi voltage LED lights with the exception of the taillights so I bought military style replacement taillights that used 12 v LEDs:

At just over $200, they were 'pricey' but, hey! It's only money right?

Pulling is home from Topeka in a two door was....exciting. The clevis hitch was 29 1/2 inches off the ground when the trailer was level. As my 2 door sport's hitch was only 20" off the ground, the rear end of the trailer as stuck up high enough in the air that the rear view mirror was useless:

The next problem developed as soon as we hit the pavement for the ride home. The trailer weighs about 1500 pounds and can can carry up to 1900 pounds so with typical military efficiency it has rather stout suspension. When traveling empty, the suspension will severely bounce when hitting any bumps and don't even think about hitting a pothole. And the tongue weight is 225 pounds so my poor JK Sport, sagged down in the rear far enough that my headlights were illuminating treetops and blinding oncoming drivers.

But, it pulls really nice, the surge brakes work excently and the only problem we had getting home was that passing drivers, particularly those in off road vehicles would slow down while passing to look it over and tended to drift in towards us as they checked out the trailer.

Once home, we decided that the 2dr wasn't going to make it because of the limited towing availability so we traded it in for a 2015 JKU and naturally we got it in 'tank' so it would match the trailer. The first thing we tackled was the insane height diference between our pintle and the trailer's clevis. My first thought was to just change out the massive HUMVEE wheels and tires (8 lugx6.5 GM pattern and 37" HUMVEE run flat tires) with something smaller. Two advantages to that is the height and also the weight. The individual wheels weigh 175 pounds each. But, we decided instead to have the hitch changed from this:

to this:

The fabricator that did this for me does really great work but it was again, pricy at $462.50.

That solved the height problem just fine:

But, I still had the tongue weight problem when hitched up. I had lifted the the JKU by two inches but the trailer when hooked up, dragged the back bumper down about five inches. So, i installed a set of Firestone Coil Rite air bags in the rear springs. With the minimum fiver pounds of pressure in the bags, the bumper still came down four inches but bringing the pressure up to 30 pounds seemed to level every thing off.

We are presently slowly relocating from our home in northern Illinois to our new home in SW Missouri. So this past Thursday my wife and loaded up the trailer with as much as we could strap in and I took off on the 500+ mile trip. At the first gas stop (which proved my MPG had dropped to just 10 mpg) i found the left trailer smoking hot. I knew it has to be either a bad bearing or the drum brake so I backed off all the tension of the military parking brakes and headed off down the road at a slightly reduced speed. At the next refueling stop (still getting 10 mpg) i found the hubs barely warm to the tough so after getting fuel, I headed off again at a speed as faster as possible. Stopping again at a rest area, I found the hubs both really hot again and I realised that maintaining 70+ mph was probably a real bad idea. I am a retired Army NCO and I know everything the military does is based on a max speed limit of 55 mph and that is usually thought to be a safety requirement. But the trailer is not happy at 70+ so once again, i baked off on the speed.

All in all, I think I ended up with a really heavy duty short trip trailer that will work great around the farmette but I am re-thinking it as an off road camper. It is just to big and too heavy for the Wrangler for anything but short trips.

Yeah, she's quite the weapon that's for sure. sounds heavier than my 10ft pop up I have. I add 30 psi to my bags, and I'm sitting with my *** 1" higher than the front, Just as my jeep sits with no trailer attached. I can pull it at 60 mph all day long without a whimper. That trailer must be a tank! I would pick up a used pop up camper, lift it for ground clearance, add some stout tires and whatever else you want for accessories and go camping. All the comfort of home pretty well. I have added a roof rack, with a clamshell case, small rack, and 2 home made water tanks that heat in the sun for showers. We also have a shower/****ter enclosure as well. I figure once I get my lift fixed up, add some AT tires I can drag that anywhere we need to go.

Sorry to hear about your troubles. I've generally seen those trailers used as a base, not necessarily used as-is. It's a terrific base to work with, and I think you'd think the same if you felt like putting some money into it.

Most who pull a trailer regularly put in stronger springs and shocks. Another good idea is to put the same wheel/tire combination on the Jeep and trailer so you only have to carry one spare (with that particular trailer, I'd go with 35" tires all around). You don't mention your gear ratio, but if you're looking to tow regularly, you may want to regear depending on what you're running now.

Did the Jeep have a difficult time towing the trailer when it was loaded? If so, you may want to do something to the Jeep's engine to give it a boost, but I doubt you had that issue. I say that because I recently did a 10-hour trip in my JKUR with a crazy-heavy, fully-loaded U-Haul trailer and my Jeep had no difficulty pulling that.

Personally, I think you got a good deal on the trailer and you've put enough into it already that it's worth keeping and continuing turning it into a great trailer to overland with. But if you decide to sell it, I'm sure you won't have any problems finding a buyer.

Curious, what are the size of those aftermarket tires and wheels on your Jeep?

The wheels are factory and I am running 31s right now.
The Wrangler had no problem pulling the trailer at all, but the tongue weight is pretty stiff. 225 lbs unloaded and I probably had close to a ton in the trailer. The Army manual shows a fully loaded tongue weight at 450 lbs and that's way too much weight for a Wrangler.

They don't look like any factory JK wheel I've ever seen and they look small, 16" maybe? P-Metric and not LT tires? Also, what axle ratio are you running? A tow package should have set you up with at least a 3.73.
