My Freightliner doesn't ride smooth. My Allegro I had before this one rode smooth. But, MrsBob86ZZ4 had to take Dramamine to ride in that or else she'd get nauseous. It rides very firm is how I characterize it. I'd rather have a Detroit than a Volvo motor. I've heard the I shift is a great trans. I don't think any of it matters to tell you the truth. What matters is the living quarters. How it's built, how it's laid out, how it works for what you want. If that rig is right for you that's it. I'm very excited for you. You should consider making plans to attend the HDT Rally
in October. It's a great group of heavy duty camper people. How about a link to the dealer's listing for it so we can drool?
