Hi, I spent the last 6 months pondering this and came to the conclusion that the Dunlop system as sold by Marcle leisure was the best bet on a sprinter based motorhome, because the top bracket spreads the weight over a greater length of the chassis member.
However having read the American sprinter forum were they have far more sprinter conversions than we do in this country I decided to upgrade the springs instead. There has been an horrendous thread on that forum where fitting of the Firestone system chopped the spinter chassis in half just behind the back wheels. I accept that airides are fitted loads of time without a problem and no doubt the jungle drums will beat the minute I put this on the forum, but having seen the damage I didnt fancy the consequences.
We therefore fitted an extra leaf in the rear springs, other people have also chosen this route. The extra weight is about the same and the cost is less than half at £250, the stability is much improved.
Our extra leaves were manufactured by Midland motor springs from near Nottingham
