Daily Driving a Square Suburban

[RyanAK]

Hey, man. Not sure the undercoat would help with rust, but it's worth looking into.

I'm with ya on the stock tires and almost always run something slightly larger as long as there are no rub issues. 2" larger only lifts the truck 1", so probably no impact to drag, but it does make a bit of a difference in engine rpms.

Hopefully whatever I track down won't need an engine immediately so that I'll have time to fully consider the options. You're right... most of the internet builds are more performance based rather than a mix of performance and economy. I'll bet you see a bit of improvement once that 383 is broke in.
