Enclosed trailers

Do any other guys roll with enclosed trailers? I am a GC with a heavy focus on finish carpentry. So I basically need to haul site stuff such as scrubbers vacs and trash cans. As well as saws and tools. Years back I had a 16 + V and it was way too large. I don’t wanna make the same mistake in the opposite direction and go too small. I am considering a 10 or 12 plus V. Any input? Also which brands do people like best for durable and simple?
