Agreed. Get a carport or lean-to and a catAgree with John - get an inexpensive hoop shed (Harbor Freight etc) 12x20 and keep it covered out of the elements. Even a lean-to or carport so its protected.
Tarps are not great - critters like to make nests, they trap water etc. - an open lean-to or carport lets air thru and less critters take up residence.
I put up a lean-to that has most of my implements under it, for under $1k, with a metal roof. No varments bother anything.I would like to but everything is so costly.
