  • Heavy Duty Skid Rollers for my 45 RV
  • Yes we do have some rollers available for your 45' RV I recommend the Ultra-Fab Steel Jumbo Roller for Trailers and RVs part # UF48-979023. This is a steel roller versus the lighter duty Ultra-Fab Skid Wheels for Low-Profile RVs up to 30' Long part # UF48-979011. It really depend on exactly how hard you bottom out if they will really hold up or not. Physics right!! I have seen frame mount hitches ripped off of an RV because it bottomed out so hard.

  • How To Find the Correct Skids Wheels for an RV
  • In order to choose the correct set of skid wheels you'll need to measure the square body on the trailer hitch and then choose the correct ones based on that. The Ultra-Fab Hitch Mounted Skid Wheels part # UF48-979017 for example are designed for a 2-1/2" square tube and the part # UF48-979018 are designed for a 3" square tube. If you have one of these two then the wheels will work well although they are technically designed for motorhomes The Ultra-Fab Rotating, Hitch Mounted Skid Wheels...

  • Skid Wheel Recommendation for 2015 Itasca Ellipse Class A Diesel Pusher
  • From my research, I found that your Itasca Ellipse is just shy of 43 ft long. The only option we currently offer for RV's that are 34 ft or longer is the Ultra-Fab Skid Wheels for Class A RVs 34' and longer - 6 inch Diameter, part number # UF48-979013. However, none of our skid wheels (including these ones) are recommended for use on diesel pusher motorhomes due to the extreme rear-end weight of the motorhome, which would shorten their lifespan. The replacement casters are available...

  • Comparing Ultra-Fab Steel Micro-Roller and Jumbo Roller For Trailers and RV's
  • The main thing I would look at is the surface area between the Ultra-Fab Steel Jumbo Roller # UF48-979023 and Ultra-Fab Steel Micro-Roller # UF48-979021. The Jumbo Roller is going to have a slightly larger surface area with the size of the roller being larger 2-1/2" diameter vs 2" on the Micro-Roller. This will lead to less sinking in on softer asphalt surfaces that you may encounter and the wheel will more easily roll over small rocks and debris on the road surface.

  • Recommended Skid Wheels For A 32 Keystone Montana 5th Wheel Trailer
  • The easiest skid wheel we carry to use is the Roadmaster Rollaway Trailer Hitch Protector # RM-050 which simply connects to a trailer hitch with a pin. That being said it doesn't look like your 32' Keystone Montana has a trailer hitch, based on the pictures you provided. If you wanted to add on a hitch there are adjustable trailer hitches like the Curt Adjustable Width Trailer Hitch Receiver for RVs # 13703, which can fit a frame width of 22" to 72" wide. You'll just need to measure the...

  • How To Choose Correct Skid Wheels for 5th Wheel Trailer
  • The steel rollers really all do the same thing, the main difference in all the options you see is how they mount. If you have a trailer hitch with 2-1/2" x 2-1/2" crosstube or 3" x 3" crosstube then the best option is the Ultra-Fab Hitch Mounted Steel Rollers part # UF48-979017 or part # UF48-979018 as they simply bolt to the hitch with u-bolts, no drilling or welding required. If these won't work then the next best option is the Ultra-Fab Steel Roller for RVs with 2" Trailer Hitches part...

  • Skid Wheel Recommendation for 40 Foot Class A Diesel Pusher
  • While we carry some very solid products when it comes to skid wheels, such as the Ultra-Fab Hitch Mounted, # UF48-979017 that you linked to and the even stronger Ultra-Fab Skid Wheels for Class A RVs 34' and Longer, # UF48-979013; these are not recommended for use on diesel pusher motorhomes due to the extreme rear-end weight of the motorhome. I reached out to someone in the Ultra-Fab Engineering Dept. for suggestions, he stated that they do not produce anything that listed as surviving...

  • Skid Wheel Recommendation for 43 Foot Fifth Wheel
  • The skid wheel part # UF48-979023 would work well for you as it's the largest size we have to fit your trailer. This shouldn't hurt your frame strength either. The more you have the better it will distribute the weight. So going with one on each side and the center will work best.

  • Can Skid Wheels be Used on a 2018 Tiffin Open Road 36 Coach for Ladder Clearance
  • Although I don't know what size skid wheels you currently have, you can use some of our skid wheels for a Class A RV like your 2018 Tiffin 36. The part # UF48-979012 that you referenced has 5" diameter wheels and is rated for a Class C RV. For your Class A RV I recommend the part # UF48-979013 which has wheels with a 6" diameter instead. These come with a 1 year warranty.

  • Do Ultra-Fab Skid Wheels Have A Weight Capacity
  • Skid wheels, including the Ultra-Fab Skid Wheels for Class C RVs up to 34' Long # UF48-979012 are not designed as fully weight-bearing entities so they do not have an official weight capacity. They are only meant as a stopgap for occasional use to prevent your RV from contacting the ground. I have added a link to a video review for you to check out as well of the Ultra-Fab Skid Wheels for Class C RVs up to 34' Long # UF48-979012.

  • Roadmaster Rollaway Trailer Hitch Protector With Hitch That Has Chain Tabs Below Receiver
  • The Roadmaster Rollaway Trailer Hitch Protector # RM-050 will likely work with your trailer hitch that has the tabs on the bottom of the receiver as there does not look like there is going to be any interference. So long as the tabs are completely on the bottom of the receiver you should be fine.

  • Can Skid Wheels be Mounted to Bumper on RV
  • You will want to avoid installing the Ultra-Fab Hitch Mounted Skid Wheels for RVs # UF48-979015 on your bumper as your bumper will not be able to resist the weight of your RV since it is not structural. I recommend installing the Ultra-Fab Skid Wheels for Low-Profile RVs # UF48-979011 instead. These can be installed on either your RV's frame or a frame-mounted trailer hitch receiver. You will need to have the brackets welded on before bolting the skid wheels to them.

When you have these welded on you will want to have a spacer block welded between the frame of the trailer and mounting bracket of these roller so that they stick down the right amount.

  • Skid Wheel Recommendation for a 2014 Forest River Grey Wolf
  • Generally speaking, skid wheels are selected based on the length of the trailer. But since your trailer is fairly close to the ground the 4 inch diameter skid wheels # UF48-979011 would be what I would go with. If you went with the 6 inch diameter wheels # UF48-979013 they would decrease ground clearance and make contact before the 4 inch wheels.

  • 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...

  • Recommended Location to Install Skid Wheels on RV with 5-Inch Square bumper
  • Generally an RV bumper is designed to take lateral force but not the vertical force it would encounter from having skid wheels installed on it. The RV frame at the rear (near the bumper) is the best place to mount skid wheels. If there is a hitch on the RV that too can be used as a mounting point. The plate included in Ultra-Fab skid wheel kit # UF48-979011 is what the skid wheel itself attaches to after the plate is welded on, and you are correct that the bolt heads do sit on the top...

  • Trailer Frame Roller Recommendation for Low Ground Clearance 1966 30 Airstream Trailer
  • The Ultra-Fab Rollers part # UF48-979021 that you referenced should work well for you. The overall height of this roller is 2-1/4 inches so while the roller would contact the ground sooner than without the roller it will help prevent damage to the undercarriage of your trailer.

  • Skid Wheel Recommendation for a Camper Bumper that is 4 inch by 4 inch
  • I went out into our warehouse and pulled a set of the Ultra-Fab Rotating, Hitch Mounted Skid Wheels # UF48-979014 and found that the distance from the bottom of the wheel to where the bottom plate will be is 5-3/4 inches. Since the bumper you plan to install the skid wheels on is 4 inch by 4 inch you will need to go with a weld on set of skid wheels like the # UF48-979023 or # UF48-979021 or the bolt-on type # UF48-979015 that includes 4-3/4-inch-long mounting bolts.

  • Best Skid Wheel Recommendation for 30 Foot 5th Wheel Camper

I attached a picture that shows these attached to a trailer frame as well. These don't have weight capacities, but instead have trailer length recommendations. This kit is designed for up to 30 foot trailer so based on that this would be what you need.

  • Mounting Orientation of the Ultra-Fab Skid Wheels for Class C RVs up to 34'
  • You can install the Ultra-Fab Skid Wheels for Class C RVs, # UF48-979012 the way you describe but yes that would change the stress as you identified. 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.

  • What Is Weight Capacity Of Ultra-Fab Skid Wheels Item # UF48-979013

The best location to weld on these rollers is at or just behind the point where the trailer's frame is making contact with the ground.

  • Skid Wheel Needed for Coupler with Safety Chains Loops in the Way of Hitch Pin Mounted Wheel
  • Since the location of your hitch pin hole and the safety chain tabs don't allow you to use a skid wheel like part # UF48-979020 or # RM-050, the only other option that may work is if you welded a skid wheel like part # UF48-979021 onto the bottom of your hitch receiver. The only issue with this is that if you have a fairly hefty vehicle it may not hold up very well as there is a note not to install it on a diesel pusher motorhome.

I do want to mention that swivel casters are for motor homes up to 30 ft long.

Ideally, you'd want to mount the wheels to something substantial as far rearward on the underside of the trailer as possible. You can see product description video of the skid wheels by clicking the provided link. I've also linked you to the installation instructions.

  • Can Skid Wheels be Used to Help Keep 5th Wheel Trailer from Bottoming Out with Steep Driveway
  • You definitely can install the Ultra-Fab Skid Wheels # UF48-979013 on your 42' 5th wheel but it is worth noting that the wheel and caster plate measures 7-1/2" tall so if the 16-1/4" that you measured is from the frame rail then that means your ground clearance will be reduced to 8-3/4" which really isn't much at all. If your frame sits below the skirting on your 5th wheel trailer then you should be able to use a shorter option like the Ultra-Fab Steel Micro-Roller # UF48-979021 which...

They said there is no weight capacity listed because it is not designed to bear a constant weight.

  • Replacement Wheel For 6 inch Ultra-Fab Skid Wheels for Class A RVs # UF48-979013
  • Each size wheel is meant for a certain type of motorhome. Class C motorhomes tend to be smaller than the class A motorhomes and that's why the 5 inch Ultra-Fab Skid Wheel # UF48-979012 is for Class C motorhomes and the 4 inch Ultra-Fab Skid Wheel # UF48-979011. So since certain wheels are meant for certain types of motorhomes, it's safe to say that they do not have the same strength capabilities. If you just broke the wheel here is a 6 inch replacement # UF48-001013.

Swivel-type skid wheels such as # UF48-979012 will not cause the trailer to swing since they will be engaging the ground only very briefly.

  • Recommended Skid Wheels for a 2017 Winnebago Fuse 24 RV
  • There are 2 styles of skid wheels that people install on their RVs - frame mount (which weld on) and bumper mount (which bolt around the bumper). For your 2017 Winnebago Fuse 24 I recommend going with a frame mount option. The Ultra-Fab Steel Micro-Roller for Trailers and RVs # UF48-979021 is what I recommend going with. They will need to be weld onto your frame (by a professional welder) and prevent damage to the undercarriage of your RV. The roller itself is 2 inches in diameter and...

  • Drag Roller Recommendation for Boat Trailer with Prop Protector Cut Out
  • For your application there really is only going to be a weld on solution that's reasonable like the part # UF48-979022 that you referenced.

  • Can Ultra-Fab RV Skid Wheels be Used on a 10,000 Pound 5th Wheel Trailer
  • Ultra-Fab Skid Wheels # UF48-979012 are designed for Class C RVs up to 34 feet long but do not have a weight capacity. A 10,000 pound 5th wheel trailer is going to weigh less than most 34 foot Class C RVs though, and the full weight of the trailer won't be on the wheels, so you can use them with your trailer. The same goes for # UF48-979013 which are designed for Class A RVs longer than 34 feet.

  • Trailer Hitch and Bike Rack Scrape the Ground when Going Up Inclines with 2006 Honda Odyssey
  • Roller # RM-050 is a good option for a Class III trailer hitch on your 2006 Honda Odyssey. It does hang down lower than the hitch receiver so it will actually make contact with the ground sooner than if the roller were not on it. This roller will not help with the Kuat bike rack though. What might work better is to use # D210 and put the bike rack in the upper receiver. This will raise it up higher and keep it from scraping on the ground, even if the hitch does scrape.

  • Can Ultra Fab Skid Wheels Install on a 2014 Keystone Cougar 333 MKS with Bike Rack

That's what I was able to find pictures of online when I searched your trailer. I don't see any reason the Ultra Fab Wheels # UF48-979013 couldn't also fit the frame before the bike rack though. You would just need to install them on the frame side of the RV before the bike rack.

  • Skid Wheel Recommendation that Won't Damage Black Top Driveway for a 23 Foot RV
  • To avoid scraping up your driveway I recommend going with the urethane wheels such as # UF48-979014 or # UF48-979015 because they are much less likely to damage the driveway compared to steel rollers. The steel rollers you mentioned are all basically the same with the exception of the sizes of each. But they are a little more low profile so they would not make contact with the ground as soon as the urethane coated wheels.
