Are you going to poly your mattress and cushions too? If you have this much mold then you need to ventilate your rig.
Do you have covers over your roof vents so you can leave them open a bit? If not then this should be your first step.
Mine is parked in my yard and we are a mile from the Atlantic and except for a little growth on the rubber roof, my rig stays dry.
Hi neighbor.....What you are seeing is normal here on the coast. I looked at mine last week while on the ladder waxing the sides, and mine has a red tinge of mildew that I need to take care of. There is just no keeping this stuff off the roof for long.
I use Ortho Home Defense Max around the outside every couple months and so far, so good.
I just saw a great news story about the best mosquito repellent for the body and Deep Woods Off was rated #1. Those clip on units and foggers did little to no good at all.
Come enjoy yourself and don't worry about those bugs. They don't eat too much.
The tires air pressure will have a great deal to do with the comfort of your ride. I have an ex rental from CA and the tires had a max pressure of 80#. I run the rears at 70-75 and the fronts at 65# and the ride is quite comfortable.
Are the spring steel pieces still in the top of your vent pipes? If so then you can make new caps that will never, ever deteriorate. I replaced my 3 vent caps with aluminum cat food cans turned upside down and riveted to the steel piece. I painted them white and they look purdy.
I have a 2004 Four Winds Majestic 28R which was an ex rental from
Cruise America. It's been darn near trouble-free. On the flats of FL putzin along at 60 I get a steady 10 mpg.
Keep up with your roof seam sealing and all should be well.
I had to educate the FL DMV about this very same issue. I have a 2004 and had it registered as such in AZ. Here in FL they tried to register it as a 2003 because of the chassis VIN came up as such.
It was a quick call to the manufacturer (Thor) to get a "Certificate of Origin" which informed DMV what they should have already known.
It's easy to get that cert if the manufacturer is still in business, but so many are not and that makes the problem much more difficult to sort.
I had the same problems as you when I lived in Navajo County, AZ. The dust storms would fill the felt window tracks with so much grit, the power windows were practically useless.
So, you must clean the side felts and also the felt wiper that is at the bottom of your windows. Wipe and wipe again with a water soaked rag.....after vacuuming out whatever grit you can. I wouldn't try using any type of lubricant on the felts because it will only attract more dirt.
