We had a 91 Pace Arrow and my dad had an 89 Pace Arrow, both on the P-30 chassis. The fact that ours had fuel injection and overdrive transmission gave us 8 MPG vs. my dad got 6.5 MPG running together over the same roads. All the parts in a 26-year-old motorhome are replaceable, look for age and operation of all the components. Our exhaust manifolds cracked, but were easily replaced with better ones. Also, the transmission failed and had to be replaced. Later models had Allison transmissions, which are way superior to the Chevy ones.
