Drop receivers??

[porscheracer]

As you may have noticed (from my siggy pic), my primary toad hookup is not good - from a safety standpoint. The baseplate on the toad is ~7" higher than the receiver.

I have researched, and the only practical solution I have found is to get an 8" drop receiver and install it upside down - raising the hitch point on the coach. Since there will be no vertical load, to speak of, I didn't foresee any problems with this. However, I'd like some input from someone better versed on the physics of this particular application than I.

FWIW, the hitch is rated at 10K, 500# vertical (? curious in itself ?), the drop receiver is rated at 5000/500, and the load with the toad is 4480/50. The toad has coach activated brakes, and they work. We have towed it >11,000 miles without incident.

Norm,

Here's a clip from Tow Bar Angle and Height Discussion in MH - Towing Issues and Toads

Correcting the problem

This is the easy part. Blue Ox manufactures a complete line of drop receivers. They range in drop from 2 to 10 inches in increments of 2 inches. These drops can also be inverted in the event that the baseplate is higher than the receiver hitch on the coach. Along with the drop receivers (pictured somewhere) Blue Ox also manufactures what we call a hitch immobilizer which can be bolted to the drop receiver and the receiver hitch to keep the slack from allowing the drop to move around too much. I would encourage all dealerships to have several of these drops and immobilizers on hand at all times. They are a quick sale, and an even easier install. It sure beats dealing with issues down the road that were caused by too much height difference.

One issue to be aware of, is the greater the drop, or rise in this case using a drop hitch, the more torque or leverage is applied to the MH receiver.

Some MH hitch receivers have broken from the excess force, but I believe they were hitches that use a round cross bar as opposed to a square one.

BTW, the 500# vertical rating is the maximum tongue weight of a trailer.

As you can see from my avatar I tow a 4X4 on 37in. tires. I've been using the inverted drop hitch for years without a "hitch".

I had the base plate custom made with detachable drop down receivers but was still too high. Shop said there were no problems using the drop receiver. Having the rig higher is very dangerous in a panic stop situation, especially mine which has a custom iron bumper with detachable winch installed. It would probably end up in the living room.

I'm not versed in the law of physics but have used it for many years.

Good luck.

Norm,
Did you consider a drop receiver rated a 10K #?

[SargeW]

Norm, I have been using a six inch drop receiver inverted for over two years without issue. As a matter of fact, I also use a surge brake system that allows the blue ox tow bar to slide back and forth about two inches when the MH brakes. Works smooth as silk with my 5K pound Wrangler Unlimited. The tow bar is nearly dead level.

With a fairly recent purchase of an Explorer with 18" wheels, I had to increase my 4" inverted drop receiver to 8". I've towed this way with no issues. I do think a good proportional brake system for the towed vehicle helps minimize the excess torque placed on the receiver using these set ups.

[porscheracer]

Thanks, all! I have an 8" drop hitch ordered from my dealer (he gave me the same price as the 'net dealers, with no shipping charges).

I ordered the one from Blue Ox (to match the Aventa LX towbar), along with 3 of the Immobilizer II's (2 fot the drop hitch setup, plus one for the View).

GaryKD: The only 10K I saw was the adjustable one. Couldn't see the value / price.

[SCVJeff]

Being anal about appearence I opted to have one made at great expense that not only fixes my problem, but tucks nicely back toward the coach so as also not extend that hitch any further than necessary.

And it looks good too..

Its amazing to me that with a diesel towing a Saturn the tow bar was level. Going to a gasser I had to use a drop "down" hitch and I had to get two immobilizers as I did have play in the connections..

Now I read where you guys with the taller connections have to go up to make the tow bar level. Never thought of it before. I can see where a good braking system is a must or look our Moho rear end with an emergency stop.

For answers to any technical questions I would go to the horses mouth ei: the folks that know. The manufacturers of your equipment. Safe Miles and Happy Travels to All

I bought a double drop hitch so I could use my bike rack.I wasnt happy about the movement and play.Rattled alot.

porscheracer,
Go here to read about the horizontal forces and weight multipliers that are in play when a panic stop is under way. With a good braking system the weight forces mentioned should be neutralized. One never knows if everything is in sync between the coach and toad brakes. Because your toad is near the maximum rating of the drop receiver, I just wanted to make sure you are aware of the potential problems and at least one choice to reduce the risk.

Go here to see the 10K weight rating drop receivers from Roadmaster.

Blue Ox makes 3 different types of hitch immobilizer. Click HERE. They are a little expensive, and with a drop receiver or extender, you need 2 of them. I think Roadmaster has something similar.
