Hey @AlexTheMan - sorry to see you go, but I understand the explanation completely.
I may be going in that direction soon, myself as well - still working out the details but, when I do, I will let this wonderful community know of my plans.
You're going to enjoy the 5.3L Chevy engine. I am still running my 2001 Chevy Tahoe LS with the 5.3L. It has been trouble free after 133K miles of service. I hope to keep running it as long as I can.
