Hi Tusky

I just measured ours 17 inches or 425mm under the rear cross member which is about 125mm from the rearmost point 17.5 inches or 432mm to under the rear valance there is about 100mm travel either side of normal.

We had a similar problem when I moved to Poland with my existing MH.

We did the profile to scale and created a plan to re-profile the diveway so that the MH goes in and out on two different gradients, thus splitting the angle into two lesser ones, so that the overhang has passed the first one before tackling the second one.

I am not sure if this description is clear. Mathematically is we previously had one gradient of 1:10 we now have a 1:10 transferring to a 1:5 so the two transitions are equally 1:5 (figures picked for illustration only)

I too had this problem. I fitted Air Rides and was able to raise the rear by over four inches. Had to fill with water off the drive though! Our drive also caused problems for cars with a low front or spoiler.

My issue was with the road/pavement as the road had a very steep camber and then we had a steep uphill drive. I wrote to the council and explained my problem and they modified the pavement to help solve the issue while they were re-surfacing the pavement!

air ride

I cant say just now as I stable it on a caravan park but I drove on the drive and also reversed on. Also I always drove on pulling a fiat500 on an a frame before I unhitched it never had any problems
hope it helps you

Hi Martin

At the risk of sounding dumb, am I correct to assume that RWD stands for rear wheel drive?

My ideal is a larger motorhome but departure angle will always dictate what I can and can't have as I am knocking on the door of 10% with 50mm clearance.

Yup, our slope is 1:10 on average but there is a small area of 1:5, so approach is critical, I want to avoid a re-profile if possible but if needs must, I guess I may have to.

Yes, the camber on the road does not help the situation for me as well.


Thanks one and all, it is good to have a cross-section of views and thoughts
