Should handle your weight just fine. I’m 6’2” and was 235 and get up on mine and other MH’s with no issues. You can of course wash most of it from the sides with a brush/wash pad on a pole if you are concerned. (Step ladder required!) I just did mine from the side using a yard sprayer to lay down some water/soap/bleach mixture, let it sit for a while and then rubbed it with the wash pad. I did it this was cause I didn’t want to move it out from the carport I have it under. I see no reason to get it perfectly clean.
