I use the camco RV solution and wash after ever trip. I have people ask if its still new and the trailer is on its forth season. When I wash I look over all the seams and make a mental note if I need to re caulk something. And I also check the room. I clean the roof 2-3 times a year with a dish soap mixed with water
Keeping the roof clean is the best thing you can do to reduce the black streaks on the sides. I wash my trailer several times each year with Simple Green Car Wash and a soft long-handled brush made for washing cars and trucks. I use the same to clean the roof. I wax it once each year - which is a big job on a 32' trailer!! But it keeps everything looking like new!
I decided to try the black streak/bug remover on the front of ours, and it worked great, except it also removed the wax. From now on, I'll just wash the bugs off the old fashioned way. Cleaning your TT will keep it looking newer longer.

No. It just keeps it looking pretty longer. It doesn't extend the life, doesn't get you better mileage and doesn't sleep more people. I don't wash things too often... My RV is parked under a carport. My truck is parked under a dirty tree. I try to wash and wax the truck once a year, mainly because of road salt in the winter.
I wash my rubber room at least once an mostly twice per season. The trailer gets stored all winter (November -April). I wax it with a wash and wax solution at least once each summer. It makes it easier to clean the bugs and road grime off after a trip. It gets soft brush cleaned after every trip. It still looks like new after 4 seasons.
Yes Dream Girl you should always keep your trailer clean and protected from the elements. We use Meguiar's Ultimate Wash and Wax to wash and Meguiar's Ultimate Quik Wax to maintain the shine and protection. A good paste wax along the way is beneficial. Always check the seals for fractures remember with an RV WATER is your enemy.
