Nice job... mine was obviously nowhere near that severe. I would guess if I had taken the skin off my slide-in, it would have looked similar to yours.
I like the fact that I was able to repair it... and let's just put something in perspective here (for those saying run away):
I purchased this camper for $1600 almost two years ago. I scrutinized this camper for several hours prior to purchase... looking for obvious signs of leaks (the previous camper I owned looked like it had rained inside).
I bought the fifth wheel hitch a the same time for another $400 and installed myself. Can't really count the hitch since it will be used on the next camper...
I purchased probably $50 worth of sealer, cleaned and resealed all the seams (based on the findings of my previous camper) to preserve my purchase... I also bought a large farm tarp to cover during periods of non-use.
I replaced all the wheel bearings just to be safe... it was unnecessary, but made me feel good. Add another $100. I used tires from my car to replace the dry-rotted ones... cost me a new set of tires on the car.
I have a day's time in disassembly, repair, and reassembly for this damage... which may/may not be everything. I have less than $75 in this repair, including three boxes of stainless steel screws at $10/box.
I will have around $300 in new vents (getting ones with fans), and exterior pieces (UV-damaged plastic pieces)... if I went cheap, I could skip most of this and spend only $40.
So for a grand total of right around $2525, I have a light 24-foot 5vr that is in good condition that I was able to pay cash for and then use the money I saved (over buying a newer $$$$$ camper) to vacation. I'm not knocking anyone, but its all about your perspective... we aren't full time RVers...
