I used to be into doing all this B.S.
I got Terminal Cancer, am almost beating it and have LEARNED that this is a WASTE of time!
Life is short when you realize that this is all junk and the time you stick into it.
Buy yourself a nice 4x4 Manual Diesel Ford or Dodge or Chev for that matter with low miles or rebuilt. Nope you won't get the fuel economy, but on the other hand, you'll have reliability, durability and a GREAT puller, which you won't get with a pip squeak TDI in a vehicle it was NEVER desined for. I've had many TDI's... GREAT for what they were DESIGNED FOR! Buy something off the shelf so you can work on it or something some FOOL aready wasted his time doing!
Forget about this CUSTOM waste of time headaches and go have fun with your family. Spend your time fishing, playing with them. This is a waste of your valuable life.
You only have a limited time here, don't waste it on chasing the wind.
