Well, I can get a full 3" PRG upgrade kit for ~$1800. I'm trying to get an estimate on the Titan swap, but I'm guessing a bit higher - could be wrong as many parts come of used/wrecked trucks. I don't know about a front SAS, but I'd have to guess its quite a bit more than the full PRG kit, and doesn't do anything for the rear.
We aren't, and never will be, rock crawlers. The same truck we offroad with is used for camping and taking the kids to daycare. {hardlaugh} I don't foresee a dedicated offroader for us, so it needs to do a bit of everything.
However, for you guys here is some
hardware porn. This guy is doing full axle swaps front and rear, plus other pieces. Around $15k in parts.
