I work as a laborer for Tiffins. I climb 10 foot ladders all day to reach the top of the slide toppers of every motorhome. I have to carry anywhere from 60 inch windows to 87 inch patios up a narrow ladder and carefully put them in brackets that I have hung on the wall. Slide toppers is usually a two man job. They start from 95 inches and go up to 320 inches which my partner and I have to hang on the top of slide outs carefully measuring every inch to go in the right place. I work with powertools, silicone and electric wiring to make sure everything is sealed and works correctly.
