Congratulations. I remember our first RV and how much fun we had. Really restrained in the monster we are living in now but have a towed car so not such a big deal. I just miss pulling into any state park or campground and being able to do just that.
We owned an 89 Jamboree and loved it.
Here are my suggestions.
Be sure to check your window seals. Water can get inside through the tops or sides easily if the old sealant is dry. It is very easy to replace the sealant with two people so you don't drop a window. Then add any color silicon over the top edge and down the sides a short ways to add additional rain protection. This is especially important if you have a front window that is mounted at a slant. Seal the top edges of the running lights as well.
Remove and replace the sealant between any vent on the roof. Use Dicor sealant versus the putty used. The sealer is self leveling and is excellent.
Park the RV with the nose about an inch high when storing so water rolls off the back versus the front thus helping with any water intrusion that might come from the front windshield.
You would be amazed how much water the overhead front bunk can hold.
If you have the Ford engine and begin to get symptoms of Vapor Lock, (losing power and stalling), with less than a full tank, hot days, heavy hill climbing. Then you probably need an in tank fuel pump.
Be sure to find any rail mounted fuel filters that may be hidden and replace them. Had one under the drivers seat along the frame that was supposed to be good for 100K miles. At 11K miles it was plugged solid. Probably from low usage the fuel varnished and plugget it.
Find a manual for your refer and follow the cleaning procedure for the chimney to remove any rust that may have accumulated. There is a S shaped baffle that hangs down inside that should be removed for a thorough cleaning. A shotgun (12 guage) cleaning brush works well.
Hope you don't think I'm throwing a blanket on your new toy. Just sharing some important maintenance items any rver should be aware of.
Enjoy your travels.
