I bought an old gooseneck trailer built on a trailer house frame for cheap at an auction. After reflooring and raising the bed above the wheels it has worked well for hauling hay. Even brought a load the 150 miles from Billings. Probably spent $1,000 for modifications, but had folks offer me that much for it after I was finished. Now, I've used it for many years, so I think it was a good investment. Still using it today.
