[63burban4x4]

great comments! unlike jhogan63, I will be driving my suburban in the winter. It can be zero here, and I like to be WARM! My son had a 65 suburban, and that truck was drafty and FREEZING in the winter.....I always thought it was partly due to the heater being designed for the single seat cab, and the suburban being so big. (and crappy weatherstripping) I plan to replace all the weatherstripping in my '63, but I've also been sitting on a schoolbus heater unit I thought I might install in the rear...haven't really thought that through, but figured if I could run enough hot water through it, she'd be warm enough to put me to sleep! It ran off a regular Ford 371V8 in the bus....and those things are HUGE inside!
I'm also addicted to AC in the summer, (probably because I'm OLD) and plan to do some summer traveling in this truck, pulling a camper, so I want GOOD working AC and I'm willing to pay for it! Sounds like the VintageAir is the way to go, but does it replace the existing heater? -Ed
