UNSTABLE WINNEBAGO

Have a 96 Winnebago 36ft. Adventurer, 8 wheeler (two in front)(six in back)(4 duel drivers)(2 drag wheels. Too much Sway and seems unstable on curves, almost lost control in a heavy desert wind storm in New Mexico. Getting ready for another long trip in a few months. Front springs have only two leaves. All rears are air suspension. There are no detectable leaks. Is their an adjustment to the air pressure to the bags, also should I have another leaf added to the fronts. Please help, Any advice will be appreciated
  • I have a 1994 33’ Class A Holiday Rambler. When I first bought it the need for new shocks was obvious. Driving it was like riding Flipper! The first thing I did was replace the shocks. It also needed new sway bar bushings and the rear end needed suspension help for the 20 years the springs had been supporting it. The steering gear was in good shape. Nonetheless, even with the still uninstalled sway bar bushings and slightly saggy rear suspension, about a year ago I set out on my +5,000 mile Grand Western North America Tour and shakedown journey. What I learned was:

    Even in an early winter storm with very strong crosswinds side-sway was not a problem, other than the push/pull effect I’d get when semi’s would roar past me at high speed.

    The only problem I had with the saggy rear suspension was the tendency to drag the rear end when I’d drive over high curbs or bad dips such as going from a street to a parking area.

    Assuming your steering gear is in good shape, simply replacing the shocks (I used Monroe Magnums) made a world of difference to my rigs drivability and if I were you I would do that first before anything else.

    I’ve since returned to Texas and am replacing the sway bar bushings both front and rear in hopes of diminishing some of the push/pull from passing semi’s. I’m currently in the process of installing rear air-bags to mitigate the rear suspension sag, there again, not for handling but rather to help with the rear end occasionally drag.

  • Is the air pressure to the TAG axle adjustable in you unit? If so the pressure might be set too low. You'll need to take the MH to a scale and weigh it and then adjust the pressure to the TAG axle accordingly if needed.
  • can I assume that that RV is not built on a dreadful P-30/32 chassis?

  • Not sure about your load or your speed. My previous Adventurer rode nice but in the high winds of the desert around Palmdale I would often have to drop my speed to 45mph to ride heavier on the ground. My Adventurer didn't have a tag but previous to that my Holiday Rambler had the tag axle. Again, speed greatly affects control. The Holiday Rambler had sway bars on the steering, which was very nice.
  • I know nothing about a Winnabago but I bet new shock absorbers would make a world of difference.
  • Well nothing is going to help out in the desert when you have high winds, you know those areas where they warn the trucks they could blow over. Slow down or don't travel during high winds.
    The tag axel is usually a fairly stable setup. Check your shocks check your suspension bushings for play. Air pressure in your tiers. You could add air bags to the front to help. larger sway bar and a panhard bar to locate the rear axel. But really not enough info to be definitive. Make shore your tag axels are working properly.
