I remember some time ago some one asked what was the best tyre inflater to use on the motor home, ( cant find the thread) mine was supposed to be heavy duty but takes a long long time to inflate my tyres up to 65-70 psi any recomendations /suggestions? also the standard lead is not long enough to reach the rear of van so i extended it with a longer lead.?apart from the length of time the compressor works ok.
