I just returned from such a trip. Bought a glider in Phoenix and drove it back to New Hampshire. I flew out, inspected the glider, and towed it back behind a 10ft uhaul box truck. That was the only easy way to get a one way rental with a hitch. It was a really good tow vehicle. No glider sway. No cruse control, but it had the next best thing, a governor set to 75. So I could just floor it the whole way home. If you want to reduce expenses, bid for something yourself on uship and bring back a load in your otherwise empty truck...
