This is our 3rd HI-LO. We started with a 1974 that we took all over the place including on our honeymoon to Cherokee N.C. Then we bought the 1977 and were in the process of repairing some slight problems when we ended up with the 1987. As a testament to the old HI-LO trailers the 74 was totaled when someone backed into it out in the driveway The insurance company paid me for it then sold it back to me for 500.00. This was about 2 Months before we went to Myrtle Beach S.C . When we came back from the trip we sold it and 1 week later it went on a 2100 mile trip with the new owner, he said all he did was pack the bearings and give it a good once over. I will try to find some pictures of the other trailers and post them if I can.
