New 24 ft camper. Grand cherokee preparation
Elmo. I recently bought a 24 foot 4500 pound camper. I have a 4.7L 2003 grand Cherokee and am wondering what some good things I can do to help prepare my jeep for the new increased load. My pop up was only 2000. All I want are your opinions !!! Thank you !

Check the 2003 "Trailerlife" Towing Guide to verify this yourself, but if your GC is an automatic, it should handle a 4000 lb trailer with room to spare. Good stuff to install are:

- Brake controller with inertia/momentum capability
- Weight equalizing hitch
- Class III receiver
- Heavy-duty shocks
- Trailer sway bar

Put these on a 20' Niagara popup (4000+ lb) that I hauled with a 4.6L Expedition and never regretted it.

I had an 01 grand with an I6. I towed a 3,000lb trailer with it for about a year. The trailer pushed the grand around pretty good. I didn't like so I sold it and got a 4Runner and it did much better.

I didn't use a sway bar or equalizer hitch with it, it did have trailer brakes. Getting a better hitch setup like MuttJockey suggest would be a very good idea.

Wdh is a must with that much weight. Keeping OD off may also help with handling, engine braking, extending tour tranny life, peak engine power and gas consumption.

I've got an 04 gc with the HO 4.7/towing package. If you don't have the towing package your engine/tranny/rear end isn't going to be real happy after a while.

The best prep I could think of for my rig and a 24' camper is to buy a truck. I'd rather spend 2k on an older f250 than tow that long/heavy with a gc. Which is why I spent 2k on an older f250 :laugh:

All kidding aside I used to flat tow my rig and camper tow using my 01 f150 and never had an issue even with a couple panic stops on the interstate. The same towed items at 40 behind my gc and it was a non-stop fight every time I touched the brakes. It does does do fine with my pop-up camper though. And I had a 20' flatbed that it did ok with, but it was never loaded heavy when I used it. Just hauling long lumber etc.

Assuming you have the tow package at a minimum you'll need good brakes on the trailer, a good controller wired in (don't think the gc has built in provisions), WD hitch, sway controller would be nice.

I think the best mod you can do is to drop the ring and pinion ration. For example if you look at truck specs, they usually increase the tow 1000lbs per .5 ring/gear ratio decrease. So the 3.21, 3.73, 4.1 would be 7k, 8k, 9k pounds.

The next thing to look at is the rear springs and what the tongue weight is. If it squats the rig down too far, you will need to something to compensate.

Also, as mentioned, the auto is the transmission you want to have (which I think you do) I would add a temp gauge to it so you can monitor that. Once the temp of the ATF gets to a certain temp, it breaks down and stops doing its job. If you have ever towed something and smelled burning ATF, you can bet that it was over heated and is now a compromised lubricant.

I added an aux tranny cooler to mine for added cooling when towing the travel trailer. Remember the wind resistance if a full height trailer does not compare to that of a pop-up. I leaned that pretty quick. Also, say buh bye to mpg. I'm around 9-11 mpg with the TT.
