Question Regarding Towing With My ZJ (4.0)

As the question states, does my 4.SLOW have enough power to pull that camper?

I believe the ZJ is tow rated at 5,000 lbs with a 500 lb tongue weight capacity? Please someone correct me if I'm wrong.

I do have a couple of questions...

1) How can I tell the weight of the camper?

2) How can I tell what the tongue/hitch weight is?

3) What is the difference between a base weight and GVWR weight?

Another question, what wiring harness do I need? I've seen some connectors that have a circular plug and a square plug.

And can I get it to mount onto my hitch like I see a lot of other Jeeps doing?

As far as the harness goes, should I get the adapter where it takes it from the rectangle 4 pin to the round 7 pin, or just keep it at the 4 pin?


And here is the numbers of my door sticker, towing is new to me so I want to make sure I know what all the numbers mean.

GVWR: 5300 lbs
GAWR (Front): 2750 lbs
GAWR (Rear): 2950 lbs

So what do all these numbers tell me?

Receiver Question

Being that I have a 2" BB lift with 31s, what receiver will I need to make the trailer level?


Would I need a standard receiver with the 2" drop, or should I go with a receiver with a 3.25" drop?

You just have to measure it and get the right ball mount. It has to be level, so put a few guys on the back of your rigand get your yardstick out. they make ball mounts from flat to 10" or so. remember, drop is not the same as lift. When you turn them upside down they measure different so pay attention.

I had an 01 grand with the 4.0. It was horrid for towing. The power sucked but that you can get used to. The issue was it was that the trailer pushed the grand around. My camper was only about 3k. I had to get rid of it after about a year. I have a 04 4Runner with a 4.0 V6 and there is no comparison. The 4Runner would get about 13 mpg, the jeep got about 9 mpg. The difference in power was night and day. The 4Runner handles so much better.

Maybe a weight distributing hitch or sway bar would help, maybe even airbags but stock or the most part it towed worse than my TJ.

Maybe it is the lack of a frame under the grand?

You want the 7 pin harness, if the trailer has electric brakes. You can get them from about any parts store. If yours is like my 01 you will pull out the panel inside the jeep on the driver side in the rear cargo area and it will tie in there. It isn't that difficult. I did take the jeep to the dealer (had the best rate in town) to install the brake controller.
