I have used a bicycle pump, the Coleman type pump, a Harbor Freight 12v pump, my home air compressor, and now have an In-Cab compressor/controller. I think I liked the Coleman type the best over the others, In-Cab excepted.
Over the years I have mounted the filler valves by the license plate, in the fuel filler door, and in the cab under the dash between the steering wheel and drivers door. Without question, under the dash was the best. I could add or remove air while in the cab, out of the wind and/or rain.
