Should have configured the 3.92. Can I upgrade after purchase?

If it was a tow behind yes it would be but these are 5th wheel Made for 1500’s. Winnebago uses hitch weight which might be a little confusing.

Not sure what you mean most 1500s can tow any of these 3 well within specs

is there any way to find out what rear diff ratio you have other than the window sticker?

Look at your RPMs on the highway. In 8th gear 3.92's with OEM 32 inch tires it will be around 1900-2000 rpm at 70 mph.

Depends on your tires. With my 3.92 and 35" tires my RPM is around 2000 at 75mph

Build sheet. If you know your VIN, add it onto the end of this URL https://www.ramtrucks.com/webselfservice/BuildSheetServlet?vin=

Haven't looked in mine, but they used to have a sticker in glove box with that information on it

I believe it is printed on the sticker that is on the rear axle.

Mine shows 3.21 on it.
