In my experience Texas side roads are as good or are in better shape than most states main highways. If you do not mind adding about 60 miles to your trip a great park to spend a day or so is Kerrville-Schreiner Park. We stayed in the deer field loop and had deer wandering through our site. You could take 41/377 from Kerrville to Del Rio and pick up 90 in Del Rio.
IMHO with as close to the border as 90 is I would only stay in RV parks and would not boon dock.
Do not know where in AZ you are heading but here is some ideas.
Take 136/9 west from El Paso and spend a day or two at Rusty's RV Ranch near Rodeo NM. Incredible night sky's since it is dark sky county and explore the Chiricahua Mountains.
From Rusty's take 80 down around and backup to Tombstone.
I'll second these recommendations. And, while in Kerrville, take the short drive to Fredericksburg to see the National Museum of WW II in the Pacific. One of the best things we've ever done. Also, one of the best sandwiches we ever ate was at Jennie's Smoked Burgers in Fredericksburg (not really a burger - so much more!).
