Video Transcript for Review of Ultra-Fab Products Skid Wheels - Frame Mount - UF48-979012

Today we're going to take a look at the Ultrafab five inch diameter ultra swivel skid wheel for the class C RVs up to 34 feet in length, and it's for a quantity of two. Now, these unique casters attach to the frame of your RV, and they help prevent tail dragging and digging in while backing up. They are a drop forged caster for superior strength to other casters, and if you notice they use extra strong metal wheels, and extra durable roller bearings, which are long lasting. If you notice they do have a Zerk fitting on the wheel here, and the Zerk fitting right here on the caster. This allows you to grease the bearings on the casters, and the bearings on the wheels. If you notice on the wheels, it also I a quarter inch think urethane layer on the outer edge of each wheel.

This provides and anti-skid barrier, and it insures that the wheel will last even longer by avoiding wear to the metal wheel.These brackets is what you'll weld to your RV, then you'll bolt the skid wheels to the brackets using the included hardware. Application again, is for class C motor homes up to 34 feet in length. The wheel diameter is going to be five inches. So, you can see if we put a ruler on that there's your five inch diameter. Does include everything laid out here on the table.

The two casters, the two steel mounting plates, the installation hardware, which is 12 bolts and nuts, and a nice set of detailed instructions.Now, one note on these. They are not recommended for use on diesel pusher motor homes due to the extreme rear end weight of that motor home. But, that should do it for the review on the Ultrafab five inch diameter ultra swivel skid wheels for class C RVs up to 34 feet in length for a quantity of two.

Unhappy with hold down, you suggest to use 21/2” u bolts but don’t supply? Only after I received product . Will not do any more business with you….


Comments
The 2.5 inch long bolts are only needed if the skid wheels are installed with the alternate bolt on method. The hardware is included for the weld on method that this is meant to be. Ultra Fab makes a bolt on application that includes 2.5 inch long bolts in part # UF48-979017

Replaced OEM skid plates with this skid wheel. Haven't driven yet, butso far it was an easy install and IMO much better then the OEM installed skid plate.

I purchased these about a year ago to try and get my 34 foot fifth wheel up a fairly steep incline to a pad in my backyard. I was a little apprehensive about purchasing these as I wasn't sure they would work - and I should have trusted my instincts as they didn't. I tried them out once and in the process of backing up the hill one of the weld joints did not hold and the wheel collapsed. I could then see that it wasn't going to be possible to get the RV up onto the pad so I called etrailer to see if I could at least return the wheels(which weren't damaged) and the bolts that came with them. I knew that I wouldn't be able to return the steel plates that were welded to my frame. etrailer told me that I couldn't return any of these since I had used them. So, I am now stuck with skid wheels that I have no use for. So, beware if you purchase these and try them out - you'll be stuck with them!


Comments
HI Timothy, Thanks for your feedback! These wheels are not meant to be load bearing. They are specifically for keeping the back of the trailer from bottoming out, saving the bumper.

This was one of the best purchases we have made for our RV. No butt bumper dragging in dips. At one campground one guy didn't wait for us to park our RV. He asked where we got our wheels, so we told him. While there we saw many people bottom out in that dip and were confident that it didn't need to be if they had put on skid wheels.


Comments
This set of wheels was the best investment we have made so far. After a years use we dont worry about dips or uneveness in the roads or driveways. These wheels take care of all the problems that have come up so far. I HIGHLY recommend these wheels.

Giving bolt hole pattern dimensions would be helpful. Had to modify my mounting plates to attach the new wheels. Look to be excellent quality.

We have a sloped driveway and have to use boards to back up the RV, which takes time and a lot of effort. The new skid wheels that we had welded to the rv works great, no more boards. We have had a number of people (with rv’s) ask us at gas stations about them. We are very pleased with this our purchase, wished we had known about these years ago.

I bought a set of the 'dolly' wheels for use under my Class C motorhome. Utilizing the on-line instructions, the job appears to be straight forward. Hoping 'dolly' wheels will end the scraping of the rear of the camper on the pavement in front of my inclined driveway. Will be waiting for warmer weather to have mounting pads welded to the frame of the motor home.

I have been very satisfied with the skid wheels. Better to roll across the surface than to grind against the ground or concrete.

  • Skid Wheels for a 31 Foot Forest River RV
    The best skid wheels for your 31 foot Forest River Forester are going to be the Ultra-Fab Skid Wheels # UF48-979012. The 5" diameter wheels are bolted to brackets which are welded onto your RV's frame. Please keep in mind skid wheels are only to help tail dragging when backing up and should not be relied upon to stop the full force of an RV from coming into contact with a steep driveway. They can help if the angle is such that the RV's rear truly does "skid" off the driveway, however.

  • Do Motorhome Skid Wheels UF48-979012 Have a Rated Weight Capacity
    RV skid wheels like # UF48-979012 from Ultra-Fab do not have specific weight capacities because they are not intended to carry a load for any extended period of time. Skid wheels usually make only brief contact with the ground. These particular skid wheels are suitable for use on motorhomes up to 34-feet and this is based on their size more so than their weight capacity. The only weight consideration for these is a general one which is that they are not recommended for use on diesel pusher...

    The Ultra-Fab Skid Wheels for Class C RVs up to 34' Long - 5" Diameter - Qty 2 # UF48-979012 and other skid wheels are not rated for load capacity because they technically don't carry a load.

  • Can Ultra-Fab Skid Wheels for Class C RVs up to 34' Long # UF48-979012 Bolt On
    To install the Ultra-Fab Skid Wheels for Class C RVs up to 34' Long # UF48-979012 that you referenced you have to weld on the mounting bracket and then bolt the wheel base to the bracket. You cannot bolt the kit directly to your trailer.

  • Overall Height of Ultra Fab Skid Wheels # UF48-979012
    The distance the Ultra Fab Skid Wheels # UF48-979012 will hang below the frame will be 6-7/16 inches. I do not recommend attaching them to the hitch. Doing so could actually compromise the structural integrity of the hitch and would likely void its warranty. The frame is the ideal location for wheels like these. In general adding air bags will not increase the ride height of the vehicle. Sometimes they can by putting as much air in the bags as they can safely hold but then that will make...

    The skid wheels I recommend for your motorhome is part # UF48-979012. This is rated for trailers up to 34-ft long and in my research I found your Thor Chateau is a little over 32-ft long. The # UF48-979012 includes brackets that are welded to the frame of the motorhome . You then bolt the skid wheels to the brackets. I would not recommend attaching the skid wheel to the motorhome hitch because it could put excessive stress on the hitch.

    The Ultra-Fab Skid Wheels for Class C RVs up to 34' Long - 5" Diameter - Qty 2 # UF48-979012 are not rated for load because they are only intended to redirect weight not bear the weight themselves. The manufacturer does not test them for weight bearing capacity due to their function, but they are extremely strong casters with a 1/4 inch thick urethane layer on the outside of the 5 inch wheel.

If too much or not, depends on the abuse you apply. These are intended to accept the abuse that would otherwise be on your trailer and then replaced if need be. I suggest you consider welding in the orientation you describe but also welding a block along side to minimize the span.
