A picture is worth 1000 words - OMW spare mount

Just a word of caution. See photo. OMW response was along the lines of not our problem. I would beg to differ if it had gone all the way and caused mayhem to the travelling public.

Took me a while to figure it out. OMW=Orbital Machine Works. And yes if that landed on the highway one can only imagine what the outcome would have been. Looks like it failed above the weld?

There needs to be gussets at every angle on that thing. That design is an accident waiting to happen. Scary.

WOW! Thank you for the identity, It could save some onesí life to know.
I have followed new RVs with the factory mounted spare tire bouncing violently. It is a rough ride back there.

I agree that gussets are necessary, but they would not have prevented that sideways-force-induced weld failing.

The design is just too high torque for this kind of construction.

You really can't safely just plug hitches together like this even though these devices are made.

It would be better to find a safe way to haul whatever is attached to this device rather than overloading hitches designed for towing a trailer.

I think the tubing was not of adequate gauge, and the welds inadequate penetration.
This does remind us all of another issue...
The rear of a trailer is no place for a bike rack.

Bouncing is just too violent.
even if the rack survives, the bikes suffer.

I don’t know about bike racks but I know you can’t beat
Thicker tubing, certified welders, fishplates and gussets when it comes to putting steel together that just cannot afford to fail. A good weld is always stronger than the two pieces it holds together and proper surface prep along with proper penetration, cleaning and surface coating (primer and paint) will go a long ways towards safe and stabile installations.
Regular inspection can often detect problems before
they become serious liabilities.

Hi: Iowa Dave... Sure sounds like a good test of your mettle. You don't want to be liable for another's situation!!!
The new owners of our former Escape 5.0 lost the spare this way too.

I'm not sure if the tire carrier was mounted on the tow vehicle or on the rear of the trailer. Could you clarify that Bryan please.

Installed by LHC when trailer was new. Installed as designed to compliment the OMW Casita add on hitch using the factory Casita spare. Nothing odd. I do a check around on things every time we use it and nothing was out of the ordinary.

From the right, I think there's a bolt-on Casita Hitch Receiver installed on the trailer, a hitch tightener, a (failed) Spare Tire Carrier, another hitch tightener, and some other item which is out of the picture frame.

From what I have seen, it appears that OMW got into the trailer accessory business, and then pretty much faded off the scene over the years, with availability, deliveries and communications getting progressively worse over time. Jim Britton retired, and I think the owner Terry Stroud is not a trailer owner.

Oh, and the spare tire carrier does not appear to have been adequately engineered or fabricated.

That's putting it kindly. You may now submit two cents to my banker, please.

A bad design can't be made good even by excellent execution. Having both bad design and bad execution.... as they say "that's gonna leave a mark"

A lot of our campers have an almost ornamental back bumper. I wouldn't trust the rear bumper for anything without talking to an experienced trailer shop. Places that customize, build or repair trailers. They know what breaks and how to fix it so it doesn't break again.

However you can't fix a bad accessory with a stronger bumper. Thanks for the heads up on this one.

I see the purpose of the angles in the omw spare tire carrier. It gets the spare tire in tighter to the trailer, but the design looks weak, as mentioned by others. 10 years ago, I bought and installed a bolt on spare tire carrier and used the bolt that comes out the back of the Casita for additional stability. The carrier I bought was not very expensive and acquired locally. It has been stable and secure for 10 years now.

IMHO, the tubing too thin, just buy a new quality unit w/ heavier metal from etrailer or local vendor?

This is a close approximation of what I found locally. It has stood the test of time and a rough ride: https://www.etrailer.com/Spare-Tire-...hy/BR56VR.html

Casita Ed your use of "the bolt that comes out the back of the Casita for additional stability" was key to your longevity. The height of of the tire mount and the considerable bounce mention in other posts would put a lot of torque on the bumper tubing. The typical bumper is not made to resist torque. Good job Ed!

Thank you. When we got home from Rice with our new Casita, I discovered the damage to the gel coat the tire left. I initially thought the way to go was the 2 inch receiver, but those who had them complained of a wobbly spare tire or bike rack. Credit to our local RV Store where they recommended bolting on a tire mount. I did, but still wasn't totally satisfied with how wiggle proof it was, so I added a 1/4 inch thick aluminum bar stock tab to the top of the mount, formed a bend and drilled it and connected it to that bolt and it is still rock solid to this day. I would love to share a picture of it, but had trouble with inserting the image I have.
