I just scored a nice 2010 Chevy 4500 Ambulance. Duramax, great condition. Except.... It's noisy. Really loud in the cab. Anyone know of any sound deadening floor mats/door insulation etc. That might help?
Has anyone been successful fitting larger tires on a G3500/G4500? I'm converting an ambulance and I'd like to go with 34" tires instead of the 30" stock tires. The rear is fine, but the front wheelwells lack the clearance. Any ideas?
