What a great trip it was. In short....
1) Arches NP
2) Canyonlands NP
3) Capital Reef NP
4) Grand Staircase-Escalante NM
5) Bryce NP
6) Zion NP
Weather in the 80s. Sunny nearly every day, with only one rain day.
We went jeeping in a jeep and jeeping in our little Toyota MR2 Spyder. Great adventures. Oh so much day hiking too.
Most nights were in BLMs, SPs, NPs, and NFs with cheap camping fees. Most travel nights were free in Wal-Marts.
Only 2 of 22 nights were spent in RV parks with hook-ups, with no battery power troubles this trip. I modified the invertor wiring as recommended by Kermit of Phoenix USA . That made it a success, along with 2 hour generator run times every other evening using the 40 amp smart charger I brought along to use in place of the on-board 20 amp charger/invertor.
I used full synthetic 5W-20 oil in the 2007 E350 chassis V10 engine which improved our over-all fuel economy by an estimated 5%. It also provided additional assurance when engine braking down long 7% grades at 5500rpm, and increased the oil change duration so I didn't have to change the oil during the trip.
The pictures I had posted are no longer available due to my flickr limitations.
