I posted this on an R-POD specific forum. Hoping to widen the audience.
We have a 2010 RP-172t. Last summer I noticed excessive tire wear on the insides of both tires. Not bald but much more than the rest. I replaced the tires but now see they sit with a tilt in toward the trailer at the top. See pic. I can't get a good pic of the axle. I suspect it's been overloaded and bent past 3500# limit. Not currently loaded in this pic so I bet it's permanently bent. We travel w/ water plus a bunch of supplies and bikes for 4 on the back. I'm reading we should fill up water at the destination and maybe move the spare tire to the truck. Has anyone upgraded the axle to a 5000#? I'm replacing the OE this spring and would like to know if it's possible/recommended.
