I have a need for a 20' 10k trailer but I don't have $4500 available to buy one. I do have a 16' 7k trailer that is in really good shape. I'm thinking about cutting it in half, stretching it 4' then adding a third axle to get a 10k rating.
I've considered selling my 16' trailer but it won't fetch much, maybe $1200, maybe.
Last summer (2017) I dumped a lot of cash into it replacing the tires, brakes, lights, springs, all the stuff that wears out. This was before the need for a larger trailer presented itself.
A friend has given me a 16' 7k trailer but it's been beat by his employees. At this point it is merely a donor trailer for the axle, tires, springs and equalizers. If the frame is in good shape I might cut it down and turn it into a 12' trailer because why not?
Has anyone ever done something this and if so were there any unexpected problems that came up during the build? I understand the donor axle might need to be cut down or lengthened and the spring perches might need to be relocated as well.
