Thankfully we were able to get out of Yuma before it got up to 100, guess it was about 9:30 am as we trekked over to the CAT scales to get the coach weighed prior to hitting the freeway. We were under the limits, a hair over 6 tons on the front axle and just a bit less than the 10 tons the rear axles are rated for. 
The TOAD weighed in at 3900 lbs, probably 500 lbs more than the Jeep.
We jumped on I-8 east toward Gila Bend, then up to I-10 and over to I- 17, it was a fairly uneventful trip all the way to the Distant Drum RV resort on the outskirts of Camp Verde.
What we did figure out is we need to map out where we can stop half way to our destinations. I have found a pretty good resource listing most rest stops since getting to Camp Verde.
