Yeah, I gotta agree with SB 400. I live in Maine and if the back roads don't kill a vehicle then the garbage they throw on the rods does. LOTS of the trucks in N.E. are so rusty & rotted...
That's one reason why I bought a truck from Georgia. Very little surface rust from the rain over the years, no rot what so ever... never saw snow, ice or salt. Good luck with your build!
