OldIHC

I found an old IH refigerator and had it painted Bahama Blue to match my restored 1970 1200. We drive the truck in a local Independence Day Parade and I would like to tow the fridge behind the truck, maybe, with the help of family distributing bottles of water and/juice boxes from it

It woul certainly be unique. I dont know anything about designing a small trailer though and I dont want to have to store a big trailer. Any ideas?

Take a look at some of the small motorcycle trailers. If you are thinking of having someone stand next to the fridge, then you will need a larger trailer. Something like they sell as a kit to put together: http://www.northerntool.com/shop/tools/ ... fgodBnQAkQ
If larger than that, then just look for a small atv trailer. be sure to secure the fridge securely.
