I've installed about 800 of these Rev 4s in the last 2 years,maybe more. Never see trailers once they leave our shop, so I have no clue about their durability. But the quality of their products are very good, great attention to detail. And American made. Out of that amount of seals that I've done. About 10 were Rev seals, not bad. I've replaced seals on new trailers that were less than a year old. These were popular seal manufacturers on these trailers. Took the course seamed really easy, but had a problem reviewing my test to see what question I missed. All in all, I recommend their products first.
