There is some confusion - at least I am confused - abuot the tire size on the Elkmont. The Trailmanor website appears to say that it has 13-inch tires, and since it is a single-axle trailer, you know that can't be right. On the other hand, some of the dealer sites (for example
this one) say that it has 225/75R/15D tires, which makes a lot more sense. Assuming these are Marathons like the rest of the TM line, they are rated 2540 pounds at 65 psi each. That should be plenty for a fully-optioned Elkmont. However, Jerry is probably right about the axle - either 3500 or 3640 pounds - so that becomes the final limiting factor.
