I used Red Max Pro on my 99 Monaco Diplomat. When I was at Lowes I noticed a cheap sponge mop next to the Red Max Pro. Since this product is intended for floor use I picked out a cheap mop that had a microfiber cloth attached to the sponge. I washed the motorhome first and then used BKF. I then used the mop to apply keeping the mop as dry as possible. I did have to be careful about drips. I used a small sponge on areas that I could not get to with the mop. Except for the front and back cap I did not have to use a ladder. I also applied one coat to the top since it is painted aluminum. I applied three coats in around three hours. I would not want to do this with a small sponge or microfiber cloth. I am very happy with the results.
