I just bought a 6'8" X 14' low profile dump, tag along trailer, last friday. In looking around on the internet, I came acoross this site, "www.harpstarps.com/index.htm".
Looks like the tarps are fairly reasonable. I think you would have to order the roller assembly and arms to fit your trailer, and it looks like the whole deal would be around $450.00.
Haven't added it all up yet, or, called them to see, but I'm also looking for something reasonable to use on this new, (used), trailer.
This one has 2' high steel sides with stake pockets on it, and I'm hoping I can use it to haul my JD 4310 TLB, and sell my 16' flatbed trailer. Been snowing here on and off since I got it home, so I haven't had a change to try it out with the tractor on it yet. But for 2K, I figure I can use it for what I need, then sell it for at least as much as I paid, = free rent.
Around here, if you don't cover your load, going to the dump, they will charge you double, and, you may get a ticket to boot.
Always amazed how many of the threads on this forum, relate to what I'm already trying to do.
