My trailers are smaller 6x10 enclosed, and 6x12 open tandem with 6’ high side boards, and not used for arboricultural uses, but using “E Track “ could be very useful for your needs
Measure the height of any equipment that you want to floor load, and space a row of E Track a bit higher, by using decking brackets you can use 2x4’s and plywood to put in removable decks above your equipment, but it is not permanent, if you need to load taller equipment
You can install the E Track at any height, or as many rows as you need for your uses. I put the bottom row just above the floor, so I could use E Track “D Rings” and standard ratchet straps to secure wheeled equipment, you can also get straps with E Clips on one end and hooks on the other, there are also all kinds of “U” and “J” hooks, bins and other equipment organizing attachments for E Track to customize your trailer for your needs
I also recommend ordering a trailer with a side door near the front, I prefer the “RV Style “ door, rather than a “Cam Bar” style door, the RV style can be opened from inside the trailer, and isn’t as susceptible to being broken into, a pad lock
is much easier to cut. Also for the rear ramp door, if you are able to get to it from the inside when loaded, put a single slot piece of E Track, or Eye screw on each side of it and use straps to secure it from the inside, then even if someone cuts the pad locks
on the outside of the door, they still can’t open it
Nope, I’m not selling E Track or accessories, but having been a truck driver for more than 35 years, I know the advantages that E Track can offer
