I totally understand when you say “the missus wants” but sometimes want and can have are totally different. Finding structural supports with the correct spacing to attach the ladder to could prove difficult! You’re also going to have the extra width of the ladder on the side of your trailer, measure to make sure it doesn’t exceed legal width. Pool noodles on a telescoping ladder work great and the ladder really doesn’t take up much room, I carry an 11’ ladder all the time for washing the windshield.
