While those generator hours are higher than average, I personally would rather have a generator that has been worked rather than one with very low hours, particularly in a 95. It may be that whoever owned it did a lot of boondocking which would account for the high hours. At any rate, 1500 hours on an Onan is nothing to worry about. Mine had 1100 hours when I sold my 95 and was working fine. The only thing I ever replaced on the generator was the starter.
HR did have a 34 foot version and it also had a tag. My DW's uncle owned one. It was exactly like my 36, but you lose the two closets in the bedroom at the foot of the bed.
The walk-thru bath was what sold us on our HR and in fact the bathroom was the primary factory in purchasing our Sportscoach. I hate the "head in the closet". Our Sportscoach has a side bath that is rather large, so while we gave up the walk-thru in the HR, we still have a decent bath.
They did also build the HRs on Chevy P30 chassis' as I've seen a few. They have larger wheels (19 versus 16). The P30 chassis does not drive as well as the F53 (I've owned both).
As far as turning radius, I could turn my HR around with the Jeep attached in my cul-de-sac if I hit it "just right". It's noteable that I can turn my 40 foot Freightliner XC in a shorter turning radius. I think it's the 55 degree wheel cut.
Oh, and I never had any problem with the HWH jacks, they had the ability to lift the entire motorhome off the ground. You don't want to do that
. Also, mine fully loaded weighed in around 18,000 pounds on the CAT scale.
