Towing
I've been thinking about ways to get a trailer to use 6 on 4.5" wheel bolt pattern, so that one could run the same wheels and tires on both parts.
So, Lippert makes the axle that's under my Jayco 174BH Baja. The Lippert is 5 on 4.5" and is a 3500# axle.
Presuming this Lippert axle is set up...
