The lack of space in the modified has been a problem so we recently found a trailer for it. No, not for the car to go on, but to tow along behind it with all the extra gear we need. Found it on a local auction site. Dunno how old it is but the wheels are 19 inch. We believe they are Austin as are the fenders. It was being used as a market stall which explains the dumb rack. The rack will go and a quick paint and visit to the signshop and it will be cool.
Guys build utility trailers that look like that from 100Gal oil tanks around here. Just cut the side out and mount it to a frame! The fenders aren't nearly as fancy, but the trailers still work great.
