We ended up trading out a truck and getting this lightly used trailer. Very nice and priced to sell quickly. The white marks along the bottom is just tape residue from the previouse owners tarping along the bottom of the trailer. Weather permitting we will have that removed. Trailer was winterized and is ready for action. Come and see it M-S 9-6PM at Progressive Auto Sales. If you would like to call Les at 208-735-5000 he would be happy to tell you more about it. Thanks!
