Best ride for the buck

Our A is a 2010 Suncruiser gasser about 38 ft long. Drives very well and rides nice. Once on the interstate, with cruise on, i can drive all day without an issue.

My A is an older (‘05) 34’ Itasca on the F53 chassis. It is very smooth & quiet, it’s like an enormous Lincoln.

I wouldn’t hesitate a moment to buy another one exactly the same if I was shopping for a newer m/h.

We went from a 1ton dully pulling a 35' 5th wheel, to a 30ft Thor ACE. The ride was better in the ACE, the noise for us was bearable. We found that for weekends the ACE was ok but for long trips it just would not work.
We went to a 07 Itasca Meridian 37' with cummings engine. What a great choice for us. We have had it going on 4 years and almost 40,000 miles. The ride is better than the ACE however DW says that with the airbages its makes walking around while moving a little harder than in the ACE. I am not mechanically inclined so I have the unit serviced once a year. That way I know things are being looked after by folks who know.
Good Luck

Longer, heavier motorhomes generally ride better than short, light coaches. It will be more difficult to find diesel coaches 36 feet and under but there are plenty of gassers in the size you are looking for. I once owned a 37 foot gas coach that road and handled very nice although the motor was a little loud at times.

We had an 2014 Jayco Precept that I hated to drive. I have a CDL, drive coaches & school buses. We put upwards of 4k in steering/handling improvements but it still was a bear to keep on the road with wind or passing semi's, the v10 though a very capable engine is NOISY and thirsty, best mpg we saw was 8.5 mph.
We traded it in for an older 07 Coachman Pathfinder, not a Tiffin, Newmar or Winnie all superior rigs, however much pricier.
We head to state parks on weekends, we don't sweat the dirt roads or the trees rubbing along the side of the rig as we head to our campsite. We paid under 70k, and it's a camper with comforts, muddy dog, accident prone grandkids, don't phase us.
I wanted a pre DEF, and a 5.9 Cummins because it's one of the best engines out there, yes it's a bit under powered at times but it's proven itself in pick ups, box trucks, school buses, motorhomes and boats. It's simplistic and parts are available, no issues getting service or maintenance done.
My hubby was amazed at how quiet this motorhome is to ride in and no bang from the expansion joints. He works while I drive.
With older units often you are limited in financing, we paid cash. It's older so be prepared to upgrade. We replaced A/C's, refrige, driver & passenger seats, plastic sinks, old faucets, upgraded all lights to LED and a new bigger inverter. Another 20k BUT it fits our needs, drives like a dream and we get 10 mpg doing the speed limit.
Figure out your wants/needs and I'm certain there is an older unit out there for you. Best of luck!
