How is the drive south from Albuquerque on I-25 to Tucson on I-10? Are there a lot of steep climbs and descents? I will be taking my 37โ Class A (Thor Challenger โ gasser) pulling a Jeep.
It is the proverbial piece of cake. We've driven it many times towing our TT and with our current Class C {usually towing my Harley}.
I'm planning on doing an "Iron Butt" ride {1,000 miles in 24 hours}, on the Harley in October and that is the route I will utilize just because the roads are so good, reasonably flat with minimal traffic for a couple of interstates {except I will take I-10 from Tucson all the way to Las Cruces before turning north on to I-25 as this will make Albuquerque a 519 mile turn around point}. The shortcut through Hatch to Deming is a good choice albeit a tad slow through Hatch but be sure and stop for salsa and chiles.
There are two places you will need to watch your downhill speed on. One in NM on I-25 (Canada Alamosa) around the 90 mi marker. It is well signed and speed drops to 65. It is a couple of long sweeping curves down into a canyon and then back up. Nothing to really worry about. The other is in AZ on I-10 around mile 320. It is the Texas Canyon downgrade, it is about 15 miles of down hill but nothing to steep. There is a rest area at the top just before the down grade if you want to stop.
