Most RVs are made from components from a limited number of companies. If you are happy with your RV and it does what you want, I wouldn't be upset that you don't see others in the campground. All RVs need maintenance, keep up with yours and when you do sell it down the road you can claim it's 'unique.' Also, not seeing others just like yours relieves you from feeling inadequate if the other unit has more accessories, modifications, or a higher state of shine.
See you down the road.
