Those HF trailers are great. If you understand their limitations, don't expect much and have repair parts on hand. WE had one worked it hard.It was kept in a covered area,1 year after we had it, paint /coating falling off, frame was rusting The only reason we purchased it... the original owner was moving that day and wanted it gone. For $75 it was worth it. For your needs, i tell you avoid them.
Craigs list it a good start for used, end of summer don't want to store it, deals. Not sure where you live in jersey(what exit) I'd buy this unit. It's 2x the cost of a HF one, but get you at least 4-5x the life.
