Hi, There is a stop-over type park--The A Bar A-- at exit 240 (Tangerine Road) in Marana.......off the I-10
They have full hook-ups; they are near the I-10.
When we go to Chula Vista we find that is a long enough day for us
If you wish to drive farther in Benson off the I-10 is Butterfield RV Park. It is a "snowbird" park but will probably be deserted at this time of year. The big draw for us is the Italian restaurant there.
These are both near the I-10. Don't know what you like? There are "fancies" around Tucson--Beaudry, etc.
