Review of the Roadmaster High-Low Adapter for Tow Bars

Speaker 1: Today we're going to be taking a look at the Roadmaster High-Low Adapter for tow bars with a 4" rise or drop. That's going to be Part Number RM-048-4.Whenever we're towing anything we want to make sure that it's going to be nice and level, so we'll show you how to measure to make sure that your flat tow setup is going to be level. First we'll start off by coming to our connection point on our baseplate that's going to hook up to our tow bar. We'll measure from the ground right to about the middle of where the pin would go through. It's right about 15-3/4".Now we can move over to our motorhome and we're going to measure from the ground to the inside top edge of the receiver tube opening. Now that's about 19-1/4", so it's about a difference of about 3-1/2".

That's just over the maximum amount allowed with our tow bar. That's where the high-low adapter is going to come into play. It's going to go directly into the receiver tube on our motorhome and we'll line up the hitch pin hole and we can put in our hitch pin and clip. Now these aren't included in the kit, but you can pick them up here at These are Part Number PC3.This is going to provide us either a 4" drop or rise to accommodate the different height differences between our setup.

A high-low adapter is going to make sure that our tow bar is going to sit nice and level now, making sure that we're not putting any unnecessary stress on the tow bar, the base plate or on our motorhome's hitch. That way we can get down the road safely and make sure everything is nice and secure.Our high-low adapter is going to have a solid steel shank, so it's going to be extra strong and have that rigidness that we need. Our high-low adapter is rated at 10,000 pounds of maximum towing capacity and it has a 400 pound maximum tongue weightThe distance from the center of the hitch pin hole that's going to go in our receiver tube to the center of the hitch pin hole over here is going to be roughly about 10" and from the center of the hitch pin hole to the outermost edge of our high-low adapter is going to be about 12-1/2". All those measurements are going to come in handy when we're looking at safety cables, because it is going to extend it out past the hitch itself, so you may need longer safety cables to make everything work.It's going to provide us a 2" receiver tube opening so we can slide our tow bar right in, line up our hitch pin hole and secure it down. Now we can just finish hooking everything up, like our electrical and our safety cables, and we're ready to go.That'll finish up your look at the Roadmaster High-Low Adapter for tow bars with a 4" rise and drop, Part Number RM-048-4..
