Video Transcript for Roadmaster Accessories and Parts RM-048-8 Review

Today we'll be reviewing RM-048-8, this is the Road Master High Low Hitch Adapter, traded at 10,000 pounds when it comes to weight capacity. It's going to have maximum ton weight of 400 pounds. This is designed to fit a two inch by two inch trailer hitch. The opening on the receiver itself is a two inch by two inch opening. If we take a measurement of the drop measuring from the top edge of the receiver tube to the top edge of the receiver tube it's going to give us a drop of eight inches. This can be used in the rise or dropped position, so if you flip it over to the rise position it's going to also give you an eight inch rise. Let's go over a few measurements real quick.

We're going to measure from the center of the hitch pin hole to the closest point here on the angle brace. That measurement is going to give us a measurement of five and a half inches. If we measure from the center of the hitch pin hole to the closest point here, that part that's welded on. That's going to give us a measurement of three and a half inches. The distance from one pin hole to the other, center on center, is going to give us a measurement of nine and seven eighths of an inch, and up top here we're going to take a measurement from the center of the hitch pin hole to the back of the shank, and that's going to give us a measurement of two inches. If you we're to go at a straight angle from one pin hole to the other, a forty five degree angle, you're going to come up with a measurement of about twelve and a half inches.

You can see here on the back side that this is a solid shank, it's a solid piece. It is going to require a five eighths inch pin and clip or a hitch pin and lock. We do sell those at, you can go to our website and type in part number PC3, it's going to refer you to a great option that's going to be a five eighths inch pin that's going to come with a clip. Please keep in mind that this is not for use with any type of trailer, this is designed for use with tow bars only. Again, it's going to give us a weight capacity of 10,000 pound with a maximum ton weight capacity of 400 pounds. That's going to do it for today's review of part number RM-048-8, this is the Road Master High Low Hitch Adapter.

Just received the order - everything was perfect! Fast shipping and appears to be a great product. Fits perfectly and solves my towing height issue. Being used with Blue Ox products (much less expensive option, and rated for more weight). Excellent value and customer service (called prior to my order, ordered via web, and received follow up). Will definitely use them again should the need arise! 130446


One year later and still very happy with my purchase as well as the service I had received. Great stuff!

Needed in a hurry, but did not opt for higher priced shipping. Item was shipped same day, and arrived fast. Very satisfied. I had previously ordered a bike carrier and was pleased to return. Best prices and fasted shipping. Will continue to use for my RV needs. 121742


Great. Adjusted tow height and works fine.

Just what I needed - Bought a gently used Blue-Ox tow-bar to pull a recently acquired 1998 Honda Honda CRV with my 2005 Jayco Grayhawk. After installing the CRV baseplate (purchased from etrailer, another great buy, installed myself in about 45 minutes) the vertical alignment of the base plate connections and the RV's receiver hitch was 9-inches off. I found this hitch adapter, it arrived within a few days of ordering even when I ordered it less than a week before Christmas. A test tow around the neighborhood proved all worked and aligned great. etrailer team followed up, provided info on shipping status, all-in-all an excellent transaction. 167517

Originally ordered a 10" High-Low Hitch Adapter and needed a 7-day (maximum) delivery date to stay on my departure schedule. etrailer responded within one day to say that there was a manufacturer's delay but they had 8" adapters in stock. This would work, so we changed order and it shipped before end of that day. I received order from UPS yesterday (one day before due). Quality, appearance and application looks great. We'll be on road on schedule and see if performance and fit meet my plans and expectations. So far, so good. Thanks. 55383

wow, I had tried to order this part about a year ago, the order went through and 40 days later I called and was told it was out of order, so, tell me, how do you sell something you don't have?, and I went my way. I decided to try again and this time got the part in 4 days, very good etrailer, I may be a returned customer now again. Part is great, super heavy duty, 31lb it will add, but I am sure it will work just fine on next trip. thanks 204575

Just received the Roadmaster 8" High-Low Hitch Adapter today and the quality looks awesome and etrailer was awesome to deal with super fast shipping and good communications, and I'm sure this is going to work just fine when I get ready to use it thanks etrailer. 65366


Have used this for a year now for my tow car and it works awesome and well built would highly recommend this to anyone needing one.

This product is fabricated well. The finish is durable, the welds are substantial and neat, as I have come to expect with Roadmaster products. As always, the service from Etrailer was quick with shipping updates and status. The parts arrived well packed using a stout carton with handles, thus no damage to the carton or contents. Etrailer knows how to pack and ship! 82548

This is a RoadMaster product and eTrailer got it to me in a few days. I was a bit surprised that the shear pin hole was so far out on the shank. I ended up drilling another one 4 inches toward the tail and will use that vs the stock hole which will reduce the stress on the receiver tube and also help a little in ground clearance over dips. 217872

by: Tom S.04/14/2015

The riser worked well as advertised. I will be using it with the folding cargo carrier I bought from etrailer a week or so ago. With the riser on the mobile home it gives the carrier clearance so it doesn't hit the ground. It also now allows me to fold up the cargo carrier. It was too close to the mounted spare tire previously. Nice. 185116

Turned it over and it raises my towbar on the motorhome so I may safely flat tow our Jeep 28855

by: Willie M04/03/2012

This is something I need and etrailer has a number of different sizes and the one I picked was an 8" unit. This should work fine on rising my Hitch carrier to he right rise from the ground. The 3 ball carrier is something I ordered in hopes I can store my interchangeable balls 36043

by: Mike S04/21/2014

Great service in getting the item I needed. The hitch adapter arrived sooner then what I would have thought it would have. Works great while towing my Jeep. The service at etrailer was great and I know where I will be buying all my needed products for my RV, yelp at etrailer! 126122

The product exceeded my expectatiions in quality and my customer service experience was outstanding. Marcia A. assisted me over the phone to identify the part I needed and expedited the order. She even called back to update me on my product. Overall I am very pleased. 136213

This drop down is so much better than we expected. It's well made, heavy duty and made the wheelchair carrier so much better. Now my power wheelchairs go up onto the carrier easily. No more fighting with the chair to go onto the carrier ramp, which was way too steep. 127038

by: JR R.06/04/2012

Great service. The 8" adapter wasn't in service, but I asked to switch my order to the 6" adapter so I could begin using the product immediately. The customer service staff switched the order immediately and shipped the product! A+ on customer service! 42740

by: Don W07/17/2014

Ordering experience, delivery and follow-through on the part of this company and especially the sales agent was excellent. Part looks great and fits the motorhome hitch perfectly. While I haven't connected the towbar yet I do not anticipate any issues. 141796

Exactly what I needed to do the job. Shipping from etrailer to my address has been nearly unbelievably fast for ground delivery. Mostly 3 days! Could be the zip code, don't know. Thank you for the outstanding services provided now and in the past. 147765

by: Charles Herrington12/05/2012

Looks very good and the shipping was excellent. It came 1 day before i expected it and just in time to use it. I pulled my car with it and it kept the towbar and the car level with the motorhome and worked perfect. Thanks for the fast shipping. 60722

by: Sylvie P.12/17/2014

worked out perfect but would have like the hole to be a little further back to avoid end play. I called Roadmaster and was told I needed 2 "magic hitch" parts which I think is redundant. As for YOUR service, shipping, etc it was excellent! 165763

Looks like the high-low hitch adapter is just what I need to raise my rod rack higher for surf fishing and driving on the beach. They even shipped it in 3 days time rather than the 7 days I paid no extra charge. 66940

by: Andy and Robin12/02/2014

It feels sturdy enough to tow a 53 footer with. A little overkill for my purpose but I will never have to worry about it. Also adds a little weight for snowy days! Fits great but got a stabilizer just to be sure. 163044

Your reps did excellent job except for one suggestion. The High-low Hitch Adapter does not come with the Hitch Pin. This should be mentioned as you must have the Hitch Pin. Keep up the good work. Richard B. 105093

The hitch adapter fits perfect. The craftsmanship of the welds are superb. I was a little worried about using the adapter, after receiving it no more concerns. 198675

Very well built. Excellent welds. Main solid shank pin hole could have been a little farther out to decrease the total extended length of receiver. 188233
