If you notice your motorhome rocking a lot, "nodding", sagging at the back or feeling unstable in wind or when overtaking lorries, there are upgrades that can help: reinforced suspension and stabilisers. They're not essential for everyone, but in some cases they greatly improve comfort, stability and safety. Here's what they are and when they're worth it.
Why a camper can feel unstable
A motorhome is tall, heavy and often has its weight distributed in a less than ideal way (a lot at the back, a lot up high). The base vehicle's (a van's) standard suspension is sometimes barely up to that weight, causing rocking, sagging at the rear, nodding under braking and sensitivity to wind (see crosswinds).
The solutions
- Auxiliary air suspension (air bags): added to the rear axle, letting you adjust height and firmness according to the load. They correct rear sag, level the vehicle and greatly improve handling. One of the most highly rated upgrades.
- Reinforced leaf springs or shock absorbers: replace or reinforce the standard ones to better cope with the weight.
- Anti-roll bars: reduce body roll in corners and sensitivity to wind, giving a more planted, safer feel while driving.
When they're worth it
It makes sense if:
- Your camper sags at the back or feels very soft when loaded.
- You notice a lot of rocking, nodding or instability in wind or when passing lorries.
- You carry a fair amount of weight or have load at the back (garage, bike/moto rack; see weight).
- You cover a lot of miles and value comfort and safety.
If your camper already drives well and feels stable, you may not need them. And remember: the first step is loading properly and not exceeding the weight limit; no upgrade fixes overloading or badly distributed weight.
Fitting and approval
Have them fitted by a professional, with quality products approved for your vehicle, and check whether they require approval (see approving modifications).
In summary
Auxiliary air suspension and stabilisers improve comfort, stability and safety in a camper that rocks, sags at the back or is sensitive to wind, without ever replacing proper loading and respecting the weight limit. The step you can take today: if your camper feels unstable or sags at the back, consider auxiliary air suspension (one of the most highly rated upgrades); but first make sure you're loading properly and not exceeding the weight, which is the foundation. Combine this with weight and MAM.
