I replaced the two Duo-Therm analog thermostats in our coach with Honeywell RTH2510B 7-day programmable thermostats. I modified them by adding a mini-toggle switch on the side to add the missing two-speed A/C fan control. They're powered by two AAA batteries that last around a year. I bought them at Home Depot for about $20 each. I've also seen them at Walmart for about the same price.
