2021 Chassis Class A Motorhomes

We purchased a 2021 Fleetwood Bounder 33C last July. Yes plug wires were a big issue as 2 days into our 6 week trip we had 3 wires fail & right front Bump Stop fall off. We waited 58 days before getting unit back. Heavier sway bars & bump stops along with a software handling Ford added made a big difference. However it still rides like a lumber wagon. We just finished a 5300 mile trip out west reaching altitudes of 10,690’. We installed 5 Star Tuning & love that, never below 45 mph or 4th gear. We drive at 70 & on flats were seeing 8.6 mpg (not towing). In mountains 7.4. Very pleased with V-8 performance. One issue all F/53 2020/2021 seem to be dealing with is ABS/Traction Control lights coming on with bumps or a speed approaching 75-76. Ours as a number have had we had a damaged Tone Ring & WheelSpeed Sensor. All seem to be on right rear. Now after 14,500 miles we are still dealing with that & it appears now to be a software problem. So far 100 days at Ford & counting!
