New to RTA looking for 4-5 days Tucson - Grand Canyon loop

[warbler13]

Wonderful site......dreaming already.

We are looking for a 4 - 5 day loop trip starting and ending in Tucson. So, we just bought a new Subaru and want to take her for a drive, and except for the following caveats we're good:
ummmm..
No $
No time

Welll, we have a little of both. But not much, so I'm looking for your suggestions about doing a summer loop somewhere. Totally open to every suggestion. We just need to get out of the HEAT! Safe, not too rushed, 2 adults.

Several things come to mind:
1. Northern AZ
Tucson > Payson? Verde Valley w/day on the river? Dead Horse Ranch campground? Grand Canyon, then home through Flagstaff?

2. AZ -- NM
Tucson > Silver City? Taos? back through N AZ?

3. AZ -- CA
a//Tucson > San Diego Beach (where?) + Mountains? (where?) North County?
b//Tucson > Kings Canyon Natl Park.....

Again we're open to anything...we like to bird, hike, car camp, motel, whatever works best.
Many Thanks in advance.
