Maxtorr, I live in High Point also. When I need chassis repairs beyond my expertise I use the Piedmont Truck Center, 412 S. Regional Rd in Greensboro. They do good work and I think the prices are as reasonable as you will find around here.
Last time I was there I had bought some tires and the mechanics cross threaded two lug nuts on the rear. They then broke the studs off. I took it to Piedmont Trucks and they fixed it plus a leaky seal in a couple of hours. They know their stuff when it comes to heavy chassis vehicles. For other kinds of repairs to the chassis I either do it myself or pay Three Points in Horneytown to do it. I keep my RV stored out that way so it's handy for inspections, etc.. Three Point Automotive is very reasonably priced. They did a right side exhaust manifold gasket for me last year for way under 200 bucks. That is a hassle and well worth it to me.
