Today I'm going to be taking a look at the Roadmaster Stowaway Storage System with rear access. Part number RM-4000-40. Here's what it looks like. As you can see it's nice powder coated steel design, with galvanized hardware. It's going to use the same quick release design that for Guardian Defense on the base plate uses. You can use your pins as well. And it's an easy access by loosening up our set screw, taking out our pin, we can lift off our bracket to gain access to the back of our coaches hinge department.
When you leave this in place while you're towing, you can simply route your wires through this nice cutout. Fits in our bracket. This is really handy if you're going to stowaway your Guardian when your vehicle is not being towed and keep it on the back of your RV, not having to use up the storage space in your RV. Now that we've covered some features, we'll show you how it goes on. You're going to slip it down. We'll put in this pin. It's included.
And clip. Then we can tighten up this thumb screw to help keep it nice and secure. Now the other brackets installed loosely in place and we're going to take our Guardian and set it in the . In there and help us adjust the distance we need between the two uprights. We tighten up our thumb screws. It's going to help insure it's in the upright position.
To keep our Guardian secure; we'll put the clips that come with it in place; we'll just take two 3/4 inch wrenches and we can snug them up. We'll repeat that for the other side. Now, you can loosen up your set screw and adjust it up little closer to your RV if you like. Then secure it. Now should you need access to the engine compartment in your RV, you can pull out the clip, take out the pin. Loosen up our set crew and just lift the entire thing out to gain access to your engine compartment. That's going to do it for our look at the Roadmaster Stowaway Storage System with rear access.
Part number RM-4000-40.

Roadmaster tow hitch with rock guard and bracket. Works great. I especially like the way the lights work on the hitch. The rock guard has protected the vehicle so far. The bracket has not been used much because I simply dont use it for short visits. Before and after tech support was super.

It’s great. It makes storage so much easier than trying to find another place to store the Guardian while at your site,and you can lock it down.

Roadmaster Stowaway is the best! No more stowing under the coach, or taking it apart and stowing in a bay taking up valuable space!
