I keep the sides lower since I use the trucks for mowing 3-4 days a week and its a lot easier to back 20-25 feet of trailer up if needed when you can see. But I put her to work doing a seeding job today with 12 yards of soil I did in 4 trips. I decided to do this because I wanted something more lasting then say post cards or new paper ads. I still did the paper this year as we try to finally build a web site and felt this would be a good way to at least have some presents even when we were not spending more on advertizing after the spring rush ends. My old gmc has high sides so when I want to move brush or a lot of mulch I do have a way to do it.
