I have also read the comments about weight, and to be honest the Jeep JK wasn't designed to carry a lot of weight. Based on the GVWR if I had a family of four and went shopping at the mall and Costco I could easilly be over the GVWR. For overland and expedition use I think that the best way to get around this on the JK would be to use a trailer. For some this may be impractical, or not the way they would want to use their Jeep, and that is fine. At the same time once you start to fit a kitchen (fridge and stove slider from Adventure Trailers,) there isn't a lot of room behind the seats for cargo.
Well I have to agree with the above. Towing capacities are generally fine for trailers; I wouldn't want to do much highway driving with any 2 door and a trailer though. But the weight is a problem when it comes to trying to take 4 people or add on too much. A lot of people don't recognise it and don't want to talk about it. Honestly if I was needing something to carry 4 for overland use the toyota 4 Runner is about the best I could see when I was looking, I think something like 1500lbs payload. Once you even everything out with fuel economy and equivalent driving range the 4 runner even beats a land cruiser...
If the following weights are correct (I found them on
http://www.automobile-catalog.com), then with the exception of the Kaiser CJ-5, it seems likely that most Jeeps modified in the last 40+ years exceeded their stock GVWR.
Code:
GVWR CURB PAYLOAD CAP
3750 2273 1477 1967 Kaiser-Jeep CJ-5 Universal Jeep
3750 2960 790 1977 Jeep CJ-5 304 V-8
4189 3097 1092 1987 Jeep Wrangler Hard-Top 4.2L
4354 3296 1058 1997 Jeep Wrangler Sport Hardtop 4.0
5401 4133 1268 2007 Jeep Wrangler Unlimited 3.8 Sport
5278 4277 1001 2014 Jeep Wrangler Unlimited 3.6 Sport
With that many decades of Jeep owners wheeling around in vehicles likely having exceeded GVWR, I did Google searches for "Jeep exceeding GVWR insurance" and "Jeep exceeding GVWR ticket", expecting to be able to read through hundreds of owners experiences on those matters. I didn't find one (but I only went through the first 3-4 pages of results). That was surprising.
Look at it this way. The CJ5, 7, YJ, TJ, and JK are really only good for expedition use with 2 passengers. As a result the remaining payload after passengers is higher... With a JKU even with only two passengers that leaves a lot of space. And to fill up all the space will most likely take you over the GVWR. Notice the Kaiser CJ5 has a much higher payload because the vehicle is lighter, lighter engine, less accessories, etc. What can you do to lighten yours? Skip out a bit on some of the really nice to have and not so much needed items. Think about it as in if you just say that at night you will drive slower than normal. Can save weight on bumpers and extra lights.
Mine is a CJ8 with 1200lbs payload capacity from stock. For example I have pulled a lot out of my vehicle and have decided against adding a lot. No big bumper with bull bars (eventually be an aluminium bumper...), minimal skids, sliders/nerf bars coming off, dash pad out, no centre console, no heater, no AC, sticking with the 258 engine - maybe eventually going to an aluminium block chevy v6... I don't carry a fridge, just plan meals that don't require it (you will be surprised how resilient fresh vegetables and fruits are from your local farmers market), dried foods, biltong, pepperoni, salami, hard cheese... All last surprisingly well. No fancy roof top tent or big camp chairs. No table. I use the tailgate as a table and chair, sleep under the stars or in a 4lb 2man backpacking tent, no air mattress just a light foam pad, stove is from my mountaineering days and runs off most any liquid fuel. Storage is duffles I can easily haul around re organise, etc...
