Yea you can and yes I do.     It's just as easy as at home.   But what I did to eliminate the need to take a hand pump along is, I put a tee in my vehicles vacuum system and hooked tubing up and routes it through the fire wall into the passenger compartment and put a valve on the end.   So I can just hook up to the cars vacuum system which provides ample pressure (actually way more than you need).
