Being able to get up and move around was probably the sole benefit to driving the RV, but even that’s been severely curtailed in many states. RV has seat belts, and out West you’re required to use them.
This particular model has a modified intake/exhaust and it is LOUD when it’s being pushed, which it always is wherever the speed limit is above 55mph. When the O/D kicks in, it cruises fairly quietly at 60; not so 70. Nowhere near.
Get it on a grade, or push it to 75 and that fat big block rumble escalates to a full-throated roar. I seriously wore industrial grade ear plugs.
The closest we came to a motor home was a 35’ 5th wheel, and surprisingly, the kids rode back there while Igor and I were in the pick-up.
It was legal for them to do so, though not if it had been our little 19’ travel trailer.
