Tripping across the Mojave on I-40

Thank you Everyone for the feedback! I learned something here about going up grades. Seems counter-intuitive, but lower gear higher RPM seems the best. We've only been rv'ers for a few years, had a TT then bought a used 2003 Itasca gas. It's in very good shape, I put some money into last year, new tires, tune up etc. I'm going to ensure cooling and brakes are done before the major trip, and anything else for that matter.

Nice head's up on gas stations.

thanks again!
