Welcome to the RV CC world. We have a 2002 36' Intrigue and have been on the road for 2.5"yrs. now and loving it, most of the time. I assume you have the air bag system and not the jacks. Ours will go up and down as the day heats up and cools down. If it does this all the time you may have a leak. Finding it can be a problem. One thing to note is when it goes down check to see where it's going down, in the back, front, r or l side. I had to replace both my rear r and l air valves.
If you want a preview of what your full time life might be you're welcome to check out our blog at: PAMPERED PENGUIN
(if you look through the whole thing you should be able to figure out the parts that we weren't loving it it may help you from going through some of the same screw ups we had.)
Good luck and happy trails.
