CCR,
Glad you got your new coach. Enjoy!
John has an excellent point. Learn your height and width limitations so you don't get stuck somewhere and have to back out or do damage. Most of us have encountered damaging situations - both to the RV and our egos - but we survive them. Some end up costing us money, but again we survive. You just don't want to be driving somewhere and come upon a low bridge without knowing your height clearance, including A/Cs and antennas. Ground clearance also is important. His suggestion about exterior wax (Protect All or something similar) will make getting bugs off easier and interior Scotchgarding of the fabrics also is good. We've always used Scotchgard when the fabric is new and it helps a lot. In this coach we have tile floors and a good grout sealing is essential to prevent spills from staining.
As to longterm care, clean it inside and outside when you get home from a trip. Don't leave the cleaning until prior to the next trip. Not only will you be almost ready to go on your next trip, but the yucky stuff won't have a chance to bake on the exterior and the other yucky stuff won't smell up the interior. After cleaning the refrigerator, keep the refrigerator doors open when storing so you don't get mildew in it. Dry the shower and sinks, again so you don't get mildew. When you clean the floor, make sure the area around the shower pan and toilet are dry, again mildew prevention. When the RV is stored, don't forget to keep an eye on the toilet water level. You don't want it to evaporate so much that the rubber ring dries out around the sliding piece. We usually empty the waste tanks after I clean the inside and add deoderant to them. Make sure your fresh water tank has a good dose of Clorox so it doesn't go bad (empty and refill before your next trip). I also leave the linens off the bed when it's stored so the bed airs out.
We have a 3M film on the front which is wonderful to keep the front paint from getting scratched. The bugs also come off it better, just put water on them to soften up and wipe off. We had a bra on the front of one coach, but it was a hassle to take on and off, as are those plastic shields. The 3M film also looks significantly better. My only advice on that is to have someone who knows what they're doing put it on because it won't look very good if someone inexperienced does it. We were lucky to have ours done at the factory where they have a 3M person who does all their work.
Mildew and its resulting odor are common in both RVs and boats. In boating, people often leave a lightbulb burning to help keep things on the dry side. If you live in a mildew-prone area, you might want to do the same thing when you put it in storage, keeping in mind that you don't want to run down the battery. This is more feasible if you can be plugged in rather than in an outdoor storage lot.
