YJ weight after swaps/upgrades?

Hey guys, looking for some input on this. My 1991 YJ is going to be going under the knife and getting a SBC/TH350 and full width axles from a 77 F250 (HP D44, D60).

Now I know A stock YJ with the 2.5 (thats what it has now) and the AX5 is right around 3000 lbs. I have researched the weight of existing drivetrain and the one going in. Its a differance of just under 800 lbs. So that brings the curb weight to roughly 3800 lbs. I then went and added approximate weight added on for Bigger tires, additional tubing (rool cage add ons, crossmembers, etc) and brackets/tabs/bracing. I ended up with a rough number of 4500 lbs (actually 4435 but I like to round up).

What I want to know is what some of you other guys have ended up at as far as final weight with all your gear and everything. I want to get an idea of what this thing might end up being one for curiosity and two for purchasing the correct tow vehicle. The wife likes the big SUVs, but I dont know that the towing capacity on the Tahoes and Expeditions is enough (its real close, but a little too close for my taste I think). I guesstimating that with the YJ and trailer + gear and people Im looking at around 8500 lbs - 9000 lbs, maybe even more.

Any input is much appreciated.

I have an 87 YJ, 4.2L, AX15, 8.5 inches of lift and 33's, My rig trail ready is at 3750 according to the truck scale at the local papermill.

I dont see where you are getting close to 9000lbs, even with the trailer and people.

A buddy of mine pulls a bogger full sized chevy on a twin axle car trailer, with a full tool box, torches and spare parts out the wahzoo, with a chevy avalanche, and he does fine.

I would think a tahoe, or expedition would be able to handle a YJ on a car trailer without any problems. Depending on the placement of the YJ on the trailer, you might need a weight distribution hitch, but the tow vehicle should be able to handle that.

A nice big 1 ton dualie would be nice to have, but not practical....Just my 2 cents.

I may have overestimated, but I would rather figure too much than not enough.

I am estimating the 4500 for the Jeep (after all the swaps, etc) and then another 2000 for the trailer itself (average 16 ft steel ranges from 1500 to 2000ish). Passengers (360), two dogs (40, yeah their tiny), all their gear for a weekend of camping (150), tools (100), water (40) and thats about all I can come up with. So that figures out to 7190. So definitely under my original estimate. I just know there is probably going to be stuff I forget, or add on later.

Well yeah!

Seriously though, I just want to make sure my estimates are in the ballpark. Nobody wants to spend the coin on a tow rig just to find out its not what they need. If the Excursion didnt have that problematic 6.0 diesel I would be considering one of those instead.
