Expert Reply:

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. The manufacturer does not give a load rating because they are not tested for this function due to the design. They are designed to divert and not to carry a load.

These skid wheels are tested on vehicles up to 34 feet long at various load capacities and have proven to function as designed to keep the trailers or motorhomes from bottoming out and scratching up panels, frames, or bumpers.

For your 30 foot 5th wheel I really like the frame mount skid wheels that can swivel. For that the Ultra Fab kit part #UF48-979011 would be your best option. I attached a picture that shows these attached to a trailer frame as well. These don't…

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. The frame dimensions are unknown so a weld solution would be better since that really doesn't matter.…

Thank you so much for the info and the pictures! According to my research it looks like your Cummins Onan RV Generator uses a 3/8" NPT Female fitting so you'll need a hose like part #100040-144-MBS. I have attached a link to all of our hose…
