I see people all the time on here complaining about handling issues and feeling like their F53 rides and drives like a bread truck. That chassis wasn't built for the amount of weight some folks haul on them.
We used to have a couple of P-30 chevy chassis class A's, and they both had poor handling. The DP has large frame, brakes, wheels & tires, steering components, and the right engine and trans to push it down the highway.
I've driven 4 different DP's. Three holiday rambler endeavor's(that's what I own), and I rented a 38' georgie boy for a weekend. Both drive really good. I can tell you that I will never own a gasser again.
