OP, you need to call Monaco ((877) 466-6226 + last six of your vin) and check on a change in tire size to something bigger than the OEM 275/70/22.5. You also need to weigh your rig loaded for travel with full fuel and at least 1/2 water before replacing your tires to confirm if you need tires with more load rating.
I seem to remember that a 295/80/22.5 is what was recommended but this was a long time ago. There is a lot of info hidden in the SEARCH BOX, especially the advance search that will let you search for things from more than the last year. Try RR8R.
