Why the need for a hybrid? I'm just curious.
Really, the reason I ask is because I see this going the same way as the Franky. I'm not trying to poop on your aspirations. I just see you driving yourself crazy with yet another cobbled build that you can't afford to make right.
You already have a killer 2WD rig that just needs a few more upgrades to be bulletproof. A Hybrid is a 2WD that will cost you so much more, and until you can afford the monster powerplant, what good will the added expense give you?
You're selling low and buying high, which just means you'll end up spending more than you need to for the same result. Why not spend a bit less and actually make your current rig work? Aside from thrashing axle boots (hopefully fixed with the $0 guard I've made), my 5T is pretty bulletproof, and a hell of a lot of fun!
If you want maintenance free, just sell your rig and get the 2.0 John linked. You can't go wrong with that build at that price. If it were closer to bonus time, I'd probably just buy the damn thing so I could have a 4WD in the garage and leave you in the lurch.
