Gravel boxes for your King Hauler

[skeeter]

The drive for the trailer chain could be driven via a servo, much like you Bruder D11 Cat conversion.

Either the transfer trailer, & CUSTOM Trk box to match it, or the SUPER DUMP, I'd be highly interested in, as I drive both, depending the day &/or job we will be doing that shift. I also drive the 7, &/or 8 axle Trk & pup combinations, as well depending the jobsite we are working at. Occasionally some Side dump work is in my week too.
