89A is not an RV route for me. I drove my pick up from Flagstaff to Sedona, there is a sign at 89A south and 17 that says limited length vehicles. There is no way in the world you want to go through Jerome. If there are a lot of fudgies parked in town it may be difficult to get through or even turn around. Drive to Jerome in your towed and report back here. :)
After boondocking at Cinder Hills orv area near Flagstaff and pulling our FW we took 17 south to 260 toward Cottonwood. We boondocked at E Thousand Trails Rd.
When we left the Cottonwood area I then took 17 to 169 into Prescott and then 89A from Prescott to Congress and noticed a vehicle length restriction sign when leaving Prescott. It wasn't terrible while pulling a 30' FW and a double tow utility trailer but some people like to bypass that section too. The view is excellent when heading south and approaching the decent into Congress.
E TT Boon89A from Cottonwood to Sedona isn't bad for rv but I wouldn't want to maneuver in Sedona. The boondock spots along 89A between Cottonwood and Sedona weren't very good, too much dirt road with minimal choices.
