Aha!
There's your mistake!! No room in my workshop shed for anything like a car, truck, or trailer!! Just tools,
lotsa tools!!
Come to think of it tho, there might be a kayak hanging in the roof trusses above the ceiling I put in a while back

Well, it's not really a 'ceiling' as such, more of a 'floor' for the 'mezzanine level' that I built so that I could fit some of my Grandad's tools & his kayak up there when I cleaned out Dad's shed and needed to find a home for his tools in my shed.
