After 9 years of crappy brakes the $1,500 (i did the install) I spent on disk brakes was the best thing I did for the camper.
Even after changing out the all four brake assemblies I was never happy. That was the biggest reason for never letting the wife drive. It's hard enough driving one of these rigs without having her play with the brake controller for different driving situations. That was the only way I could get "acceptable" braking response.
Remember too the brake cleaners sold today will never do a good job of cleaning grease soaked brake shoes, so even if you accept taking the drums off every year you would still need to buy new shoes if they where contaminated.
I get mad just typing this post thinking about the crappy drum brakes they put on campers today.
