The nice shop paper towels you get in a box is all I use if not in the house, you won't blow through those suckers.
Just do a snot rocket into the bathroom sink at the next truck stop like most drivers do right before I want to use the sink.
Depending on how big of a box of tissues you have, they make little containers that the small boxes slide in that strap to your visor, or if its the bigger ones, maybe get a couple velcro straps and strap it around arm rest of passenger seat, then would still be in arms reach.
