Review of Brophy - Tie Down Anchors - BP1D Video

The inner measurement of the Brophy D-Ring Tie Down Anchor item #DR01 is 2 1/4". I have attached a diagram with the measurement.

There is no mounting hardware included with the Aluminum A-Frame Trailer Tongue Toolbox, item #350970, due to the different construction and mounting locations that may be required for many different styles of trailers. I would recommend using a…

You can reverse with the Curt MV Weight Distribution System part #C17062 but it's recommend that you unhook the spring bars so you don't put the system into a bind. This is pretty standard practice for pretty much any weight…

The holes of the backing plate part #BP1D are round so you wouldn't actually use a carriage bolt. Instead you'd use a standard nut and bolt. 5/8 inch diameter would work great.

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…

The Class V hitch we have for your 2004 Dodge Ram 2500 with the best ground clearance is the Curt hitch part #C15809. It doesn't tuck right under the rear bumper like what you can see in the attached picture but it does sit the highest.

The bolt on the Brophy D-Ring Tie Down Anchor #DR01 measures 3" long x 9/16" diameter. The best way to mount it is with the Backing Plate #BP1D. There is not a specific T-nut available to mount this in the channel on your trailer.…

The Buyers Products Trailer Wiring Junction Box #3375601101 referenced in your question measures 6.5 inches long, 3.21 inches wide, and 2.5 inches tall when the cover is installed. The mounting holes at each end are spaced apart 7.38 inches on…

The lid of the Junction Box part #3375601101 that you referenced does not have an O-ring or seal built into it. The lid has a pretty deep channel though that fits to the base of the box well enough that it does a decent enough job keeping moisture…

It sounds like you have a junction box like part #3375601101 installed on your trailer and the brake output wire from the assemblies are ran to this but not to the trailer connector. If that is the case than all you will need is a ring terminal…

Junction boxes like #3375601101 have independent terminals for each function that don't connect to each other. It would be very possible for a connection to go bad or lose connection, but it is not normal for an entire junction box with all…
