Did it do that when you looked at the RV before purchasing it? Have you used the RV before this and that alarm did not sound? There are a lot of things that can cause this. The most common would be the Jack leveling system to level the Motorhome. Most Jack systems have some type of light and alarm that will sound if the KEY is ON and the jacks are extended. If you have Jacks and they are not extended, there could be a fault with the Jack system. You need to state what Chassis you have Ford/Chevy/Workhorse. Doug
