pull in gas up, wife will go in camper while im fueling and use restroom. i will pull to outside of parking area out of the way or in back and i will go in camper and use restroom, then do a walk around checking things on outside.
our TT is 37 footer so once in a while at the larger stations if no convenient pump is open (my truck is gas) i have pulled around back out of way and unhooked TT then pull around to pumps without TT. my wife will slip inside TT and make a sandwich for lunch break etc. by the time i get back and rehook TT we eat. we are never in a big hurry and i can hook up our WDH blindfolded.
about a year ago i pulled into a flying j truck stop with my truck not towing and pulled into the best spot for a longer TT and tow vehicle (on an end pump) as soon as i got out to pump, a couple with a TT pulled into the station looking for a pump. pumps were full on both ends so i waved to the guy to use the pump i pulled into and moved to an interior pump. his TT was basically blocking a large section of parking area, and i wanted to make it quicker and easier for him. he verbally thanked me. i said "no problem, been there myself" a little kindness goes a long way.
