Revisiting Towing

[greymud]

I have an 05 NA 5MT and plan on getting a teardrop level camping trailer in the next year-ish. I'm pretty sure the suspension is original - there's extensive documentation on maintenance. Living in the WNC mountains, I'd be coming uphill

I've been reading about TACO swaps and the like, but cant' figure out what would meet my needs/is best for suspension work before I start hauling the trailer. I'd like the back end to be a bit more rigid, but no lift. It seems a lift just adds more complexity. I'm planning on replacing the bushings - it's very squeaky - but not sure about anything else. There's a lot of options combined with limited parts availability.

Any advice? I've read all of these boards and most of nasoic and am starting to confuse myself.
