Definitely.  1 weeks national forest.  1 night CG with hookups.  Do all dumps.  Fill tanks.  Recharge.  Back to national forest.  Thrift store.  Bent & dent food stores.  Lots of great rice & beans recipes.   Solar for supplemental.  Have lots of fun enjoying nature, campfires, hikes.   I DO believe I COULD do it on half and that's saving a bit of $ each month for parts/repairs.  Not saying I'd want to, but just saying I could if I was by myself.  With family forget it.  
$1500, I'd change my tune (even with family).
Full time 2 nights national forest, 1 night CG.  All the rest of the strategy the same.
