Roadmaster's 070-series hi-low adapters help level a tow-bar connection behind a motorhome. Part numbers 072, 070 and 076 are similar 2-inch receiver adapters, but they provide different rise or drop heights. Each shares the manufacturer's 6,000-lb towing and 200-lb maximum tongue-weight ratings.
Match the height difference, not just the receiver size
Capacity matters: The 6,000-lb rating applies to the towing arrangement only within Roadmaster's instructions. The vertical tongue or accessory load must not exceed 200 lb, and the lowest-rated component in the system governs. These adapters do not raise your motorhome hitch or tow bar capacity.
Roadmaster 070-series adapter specifications
| MPN | Rise / drop | Hitch interface | Maximum towing | Maximum tongue weight |
|---|---|---|---|---|
| 072 | 2 in | 2 in to 2 in | 6,000 lb | 200 lb |
| 070 | 4 in | 2 in to 2 in | 6,000 lb | 200 lb |
| 076 | 6 in | 2 in to 2 in | 6,000 lb | 200 lb |
How these differ from a receiver extension
A hi-low adapter changes the connection height. A straight receiver extension primarily adds rearward reach. The 070-series adapters use 2-inch receiver connections and a reversible offset; do not select them solely to move a cargo carrier farther from a rear bumper. Confirm the intended application and installed clearance with the towing equipment manufacturers.
Roadmaster also sells a higher-capacity 048 series with different limits. See our Roadmaster 048 hi-low adapter guide for that separate family rather than assuming a 070-series part has the 048-series rating.

View exact adapterInstallation and towing checks
Measure the hitch and tow-bar connection heights according to the tow-bar manufacturer's directions before choosing the required offset. Follow Roadmaster's mounting instructions and use the specified hitch pins and retention clips in both receiver connections. Recheck pin engagement, turning clearance, receiver ratings, safety-cable routing and tow-bar level before traveling. For a flat-towed vehicle, do not assume a change in hitch height is enough to make the entire towing setup compliant.
Common questions
Can Roadmaster 070 be installed for rise instead of drop?
Yes. Roadmaster describes the 070 series as reversible hi-low adapters, provided the correct hitch/tow-bar geometry, clearances and installation instructions are followed.
Are the 072, 070 and 076 capacity ratings different?
No. Roadmaster lists all three at 6,000 lb maximum towing capacity and 200 lb maximum tongue weight. The primary difference is their 2-, 4- or 6-inch offset.
Can I tow a trailer with a tongue weight greater than 200 lb?
No. The manufacturer expressly limits these adapters to 200 lb maximum tongue weight, even though the maximum towing capacity is listed as 6,000 lb.
Does this replace a tow-bar baseplate or safety cables?
No. It is a receiver-height adapter only. The tow bar, baseplate, safety cables and towing vehicle must each satisfy their own specifications.
