I noticed on another post about the Jeep Jamborees and some questions about where everyone will be staying. Here is one option, even if there is not a lot of time before the various Jeep Jamborees'.
As a Jeeper, and one who has owned a few now, both 4 and 6 cylinders, I highly recommend buying a Boler or a Trillium trailer. There are many websites that cater to "Trillium" or "Boler" 13 foot fiberglass trailers for more info.
I have a 1973 Trillium (13 foot, stove, fridge, furnace, freezer and port-a- potty) now, and I pulled it with my '98 TJ (2.5L), my '88 MJ (2.5L) and to the Okanagan a few times with our '03 Liberty (3.7L) and they all pulled it quite well. The 4 cylinders are in no danger of getting speeding tickets, but the 6 bangers pulled it great, with no big gas mileage issues. If anyone with a Jeep product is looking for a trailer that doesn't involve a tent, I highly recommend a Boler or a Trillium fiberglass trailer. They are extremely light, you can get one for $2-$3 grand, and pretty much any Jeep with pull them with ease without trailer brakes and any fancy hookups or hitch situations. If anyone wants to see mine, just let me know. I love it, and wouldn't sell mine for the world, its so handy and practical. Even if you are a crappy trailer backer-upper like me, you can move it by hand into any campsite.
