Oxjockey,
You're likely to need 1(-)6 years to pay off a Featherlite. I think the name came about because they can make your pocketbook feel "feather-light". I lived in MN and was looking for an enclosed trailer. I looked at Featherlite, Wells Cargo, Haulmark, and others. The Featherlites were not lined and had aluminum floors. This was too thin skinned on the sides and made for a slippery floor. By the time I was able to spec out an alluminum unit w/ a 10,000# rating it weighed as much as a steel framed trailer. I would up w/ a 26" Haulmark Elite II. The floor, wall, and ceiling members were all 16" O. C. Something the others were not.
In the end I financed it w/ my credit union. I was handled like an RV trailer at the appropriate APR. I liked it and would look at them again if I ever need one again. The only advantage I could find w/ an aluminum Featherlite would be its ability to fight rust. That alone was not enough to justify the additional cost and its unlined walls.
