Combining a hitch extension with a rise/fall adapter?

My newly lifted Jeep Wrangler puts my Roadmaster Sterling All-Terrain tow bar more than 3" out of level. The problem is that my hitch is tucked pretty far back under the rear of the motorhome so I can't add a rise adapter without also adding an extension.

Roadmaster says it's better to use the extension and the rise adapter than to have the tow bar more than 3" higher on the towed vehicle side. Blue Ox (who I checked with since I have one of their rise/fall adapters already) says not to use them together.

Thoughts?

Thanks!

Mike

    I'd need more than 2" but it's crossed my mind. I have 4" of suspension lift up front plus 35" tires so it's quite a boost.

  • Yeah, that's all on my mind. I ended up with 15" extra length so that's certainly a bunch of extra leverage and moment arm on the hitch.

    I'll be keeping a close eye on everything and I'll probably turn up the sensitivity on my braking system a notch as well.

    We towed a JKU on 37's for a while. Just be aware that extensions, risers etc. add leverage against the receiver, so you should derate the receiver accordingly. By what amount is anyone's guess. If you have a 5k hitch then something to think about.

    I would be thinking along the lines of a custom 10k hitch and investigate the MH frame extensions to see if bracing is warranted.

    I need more like 8-9 inches from the pin hole to the rise on the receiver so the Roadmaster part won't work unfortunately.

    I haven't found one with a long enough shank either so far.


    Mike, Fire up here,(Ex San Diagon)

    We've gone through all that stuff too. Our present coach, an '04 Horizon 36GD with the C-7 330HP CAT, was also too low for our lifted '04 Rubicon. And, I wanted to carry our Honda GL 1800 GoldWing on the back too.

    Well, we ended up with a Hydralift M/C carrier/lift which, has it's own receiver mounted to it. But, that still was too far tucked under and, too low for the Ruby to be correctly towed. So, I made a combination riser and extension all in one piece. Then, because we were using the Ready Brake actuator too, that additional 12" item, kicked the Jeep back about 6 or more feet from the tip of the original receiver on the coach.

    And that was OK because I needed clearance for the Jeeps hood to the platform on the M/C carrier.

    The point here is, you do what you have to do to make your system work correctly. If you need to extend your original receiver out a few inches, then rise it or, the new one, to meet standards for as close to level tow-bar towing as possible, well, that's what you gotta do. If it's all built correctly, you'll be just fine. Been there done that, more than once. Good luck.

  • My Roadmaster adapter extends about 6" from the hitch before it rises, or falls as in my case. Maybe you can find an adapter with a longer reach???
