What other ideas are you looking for? If you've got the skills, replacing the back half of the frame with another frame section is an option, but if the frame is that bad, I'd be looking at the bottom skid mount area as well. I bet it's not far behind. A frame swap is really not any more work than welding up a back half in my opinion.

Hate to say it, but rarely if ever have I seen a frame where the back was real bad and the rest was fine, as srlbotanical said check under the skid plate on the bottom of the frame rails, that is where a lot of problems come from, however if it is confined to that area AutoRust makes a nice pre made weld in replacement piece that I have used with some success on frames with issues. If you think you can fix the frame you have I say go for it, but just be warned you will probably find more rot the further you get into it. I have spent some time in PA and I have seen the way PENNDOT lays down road salt. Thats all im sayin',

Only way to really tell is to unbolt the transfer case skid. Every TJ in this area from what I've seen has surface rust/crustiness in the gap where the driver's side of the transfer case skid bolts to the frame. Low mileage, high mileage, and age don't matter, they all do especially if they were driven in the winters of 2009-2011.

The problem is it'll look like "just minor surface rust" bolted up but once you drop that skid, you might not like what you find since the skid hides alot of frame rot easily. It'd be best to throughly check it because if your luckily, it's already been repaired by the PO so welding in the new sections in the rear of the frame would be worthwhile. If it hasn't, it'll save you from wasting time/money/effort on a frame that's already too far gone.

BTW, on another note, there is a guy in West Chester that has clean frames/tubs on Craigslist and there is Davey's Jeep not too far from for sourcing clean frames/tubs as well if do go the frame-swap route.
