What to check before fitting
Start with the outlet. Your coach's supply line needs to meet a 3/8-inch NPT female port, so look at the fitting on the regulator you are taking off. Then confirm that the pigtails reach both cylinder valves without being stretched or kinked where the cylinders sit. Finally, total the BTU ratings printed on your furnace, water heater, range and any other gas appliance; the combined figure should sit comfortably within the regulator's rating.
Common questions
Will it work with a single cylinder? It will regulate gas from one tank, but the automatic switching only does anything on a two-cylinder setup, which is what it is built for.
Are hoses included? The two 12-inch pigtails that connect the regulator to the cylinders are included.

What auto-changeover buys you
An RV with twin cylinders and a plain regulator still goes cold at 2 a.m. when the open cylinder empties. A two-stage auto-changeover regulator ends that: both cylinders connect through the included 12-inch pigtails, the regulator draws from the service side, and when that cylinder runs down it switches to the reserve on its own - the furnace never notices. The indicator shows the swap happened, and the empty comes off for refilling without interrupting supply, which is the feature that matters in January.
Two-stage regulation also holds appliance pressure steady as cylinder pressure falls and temperature swings, which is what fridges and furnaces want. Fitting is within a competent owner's reach - and finish, as always with gas joints, by brushing soapy water over every connection and watching for bubbles before first use.
