Travelers World at San Antonio TX take the all the day tour that picks up at the office.
Rusty's RV Ranch Rodeo NM it is dark sky country and the night skies are incredible and drive up into the Chiricahua Mountains.
Leave Rusty's and go to Tombstone AZ by the way of Bisbee.
About three years ago the bottom of the over cab overhang on the passenger side separated from the sidewall about 1 1/2 inches. Not wanting to tear into for a rebuild but wanting to save it here is what I came up with. Inserted the nozzle from a can of Dap expanding foam adhesive as far inside as I could go all long the separation had to two ratchet cargo straps around the cab over and as soon as I had filled the area with adhesive I tightened the straps down. With disposable rags soaked in acetone removed all of the adhesive as it came out of the gap that was now down to a 1/8 of inch. While still strapped drilled a series of 5 holes up about 2 inches from the bottom following the curve of the cab over. Then ran in screws with fender washers painted to match the cab over. After a full week took the straps off and it held and has held for about three years.
The one problem I have had over the years is sealing that 1/8 inch gap every type of caulk or sealant that I tried would crack. Several months ago I scraped all of the old sealant off cleaned it with acetone and applied clear Gorilla tape. It is has held up better than any sealant or caulk has.
Do not get confused with clear Gorilla tape and Clear Gorilla sealing tape. http://i.imgur.com/c7i2Yskl.jpg
Good roads as far as gas goes just fill up when at a 1/2 tank. Check out Alabaster Caverns State Park and just bit off the path Black Mesa State Park. FYI there are no good places for the night between Tucumcari and Albuquerque.
We extended our bed by placing a piece of plywood under the mattress. For legs cut two 4/4 posts the height needed drilled a hole thru the plywood and into the center of the posts dropped a carriage bolt down into the hole.
I35 to US54 to I40 to US54 to US70 to I10 then either I10 to 80 at Benson to Tombstone ( the fastest}) or my choice would be I10 to 80 at Steins to Rusty's RV Ranch (fantastic night skies in dark sky country) then continue on 80 to come into Tombstone from the South.
No good place to stay at Santa Rosa either stop at Tucumcari or continue on.
And just monitor the weather.
We're also going to Glacier this summer - glad to get all the input folks gave on the campgrounds. We booked the KOA on the east side of the park - one reason was that the Red Bus tour will pick up at right at the campground.
For anyone traveling with dogs East Glacier KOA has a dog walking service available so that while you are out they will come to your RV and feed and walk your pooch. Lets you take the all day Red Bus tour. We were very pleased with this KOA and the dog walking service is why we picked it. The West Side KOA does not offer this service instead they offer to have your pooch picked up by a local kennel and taken off site for the day.
