Max towing capacity?

Looking to buy camper trailer and would like to know how big I can go. I have a stock Dana 35.

Depends if the camper has trailer brakes.

I've found XJs will pull about as much as you can put behind them, stopping the load is the problem

95' XJ Country - Stock Skids - D30/D35 Limited Slip - 3" Lift - 31x10.50R15 - 4.0 HO - AX15 - NP231

98' XJ Classic - D30/C8.25 - 4.5" RC Lift - 33x12.50R15 - 4.0 HO - AW4 - NP231

There's a difference between getting a heavy load moving/rolling and towing same for long distances. On most vehicles, 4WD lowers the towing capacity as does taller (than stock) tires. According to the book, max rating is 5000lbs and that's only when the XJ is equipped with the 4.0L, auto tranny, HD engine cooling, a auxiliary tranny cooler and brakes on the trailer. ALL cooling system components must be in top notch condition before towing. If not, u'll find out real quick.

The XJ is far from a towing machine.....I mean just look at it. We've towed a meager 1500 lbs (flat trailer, 2 bikes) and u can most definitely tell 1500 lbs is back there. Tow a tall box trailer with a lot of wind resistance and my guess would be things start to get dicey quickly........but hey, somebody will be along saying they towed their 34', 4 motor offshore rig, or something to that effect, no problem. Again, it ain't a towing machine, don't guess at the towed weight/load, have the trailer weighed, as it will be loaded/equipped, at a certified public scale.

Man Law - hoods should be raised at least once a week.....have a look see.

Better make sure your truck is up to snuff.

When you say travel trailer, I am going to assume you are talking about a double axle about 16 feet long. If that is the case, there is a grocery list of requirements to do it. DON'T EVEN PULL IT HOME WITHOUT EVERYTHING ON THIS LIST!!!

1. A class 3 receiver hitch
2. A load distributed hitch assembly
3. A good transmission cooler, like a B&M. #70264 installed
4. If the trailer does not have electric brakes, put them on!
5. And of course a brake controller.
6. Common sense, and experience. I am sure you have the first one, but if you lack the second, take it slow till you get it...

I have pulled a flat trailer with a quad on board (about 1000 pounds) on 500 mile trips without a trans cooler, but any more weight than that I feel would be I'll advised.

Here's what you need:

http://www.fiberglassrv.com/forums/registry/2089/

My father towed a trailer just like this from N. California to Nova Scotia and back...to Yellowstone, the Grand Canyon, Mexico, Texas, through the southwest and all around the western states with his 1990 XJ Laredo...that he bought brand spankin' new...the one I had...and my son has now with 270K on the clock. He had a trans cooler and trailer brakes and a closed cooling system.

Something I forgot to add to the list. IF it is a flat nose camper (IE: Box Shaped) I would strongly suggest in investing in a roof air deflector.

I got one for my last tow rig, a 1999 GMC Safari. I pull a 10x6 enclosed trailer that I turned into a camper/toy hauler. Without the deflector I was getting 10.5 MPG. Once I put on the deflector, and had it adjusted to the right angle the mileage went up to 14 MPG with the same load. AND IT MADE A HUGE DIFFERENCE in the handling on the highway, especially when passing semis and in cross winds.

I plan to set it up on my 2000 XJ this weekend. I will snap a picture and post it after a test drive.

Here is a link to where I got mine. http://www.icondirect.com/categories...rs/AeroShield/

US tow ratings are somewhat lower than here across the ocean. The list provided above is pretty complete - the most important part IMO is trailer brakes. XJs (and ZJs) have crappy brakes, they will NOT stop a heavy trailer efficiently and safely if it's anything more than around 2500lbs..

XJs here in Europe (2.5 litre diesel and 4.0 gasoline 4wd versions) are usually rated for around 6500lbs (2700-3000kg) towing capacity for trailers with brakes; trailer without brakes and it drops to around 1000-1500lbs. One thing to consider with an XJ is that it has fairly short WB, which does result in a bit "snaky" handling with heavier, longer trailers. The 4.0 can pull suprisingly heavy trailers fairly easily, but it's not the most ideal if you're looking at a bigger camper.

My comfort zone would be around 20ft./ ~3500lbs gross weight trailer with brakes, class III weight-distributing hitch for daily towing. I know for a fact you can pull 5500+ lbs all day long without issues, but you're not gonna enjoy it - especially if there are a lot of uphills and downhills.

My x 4.0 xj from 1992 is rated at almost 7000 lbs with brakes. Personally I have never towed more then 3500 lbs and on flat road (which is almost all the roads in Denmark) and it will still lock up torque converter at 40mph.

You never know

Maybe the ages-old idea of the Bering Strait bridge/ tunnel project is secretly finished, and OP is driving through Alaska and Siberia, across the Ural mountains and into the heart of continental Europe
