I am a brand new MH owner (nearly!). Van is 6.9 m long. Unloaded weight 3,500kg. Been doing my homework, and discussed with Insurance provider, and intend to keep on private property at home. On grass (no other option). I'm planning to smooth out bumps and hollows, and re-inforce with some form of matting/ground protection and I'd be very grateful for tips, recommendations, other experience or advice on this ... Thank you
