Hello Bill, thanks for reaching out. We may have the parts you are looking for, but there is no way to look up your camper to know exactly what hubs you will need or to know the axle diameter. RV manufacturers just are not that specific with their online literature.

If you are needing new hubs, the best way to determine the correct replacement will be to remove a wheel and look for the number cast on the hub. Idler hubs will have a number stamped on the back, and hub/drums will have a number on the front.

If you can provide me with that hub number, I should be able to look up all the specs needed to find replacement parts. Then we can see if there are any compatible 5-lug options.

As far as larger tires, the main thing to keep in mind is the clearance in the wheel well area. You want at least 3" between the tire and the fender, and at least 1" between the inside of the tire and the frame of the trailer.

If you can tell me what size tires you are running, as well as how much clearance you are working with, I can tell you if larger tires are possible or not.
