We have a 2007 Hymer B654 plated 2100Kg front and 2400Kg rear (overall 4000Kg). The front sits very low so top of tyre is just within the wheel arch and the van seems to bottom over bumpy roads and potholes. I believe uprated springs (Goldschmitt?) are a solution. Is this your preferred recommendation please? If so could you give a price for supply and/or fitting please? Any other solutions (can't really afford air suspension) and do we need to have the front shock absorbers replaced at the same time?
