Not at all our drive slopes much the same as yours and we park on ours without problems I do put wedges under wheels just in case.Looking at getting our 1st MH soon probably 7m. We have loads of space on the drive but it's steep. Would this be an issue at all? Would wedges under the tyres be a good idea? Sorry for thread hijack.
By the way our paviours were laid on dry lean concrete as I needed to be able to park heavy vehicles on it they were sealed with a resin sealant never needed to weed or clean it much for six years but doesneed re sealing now.?
