I'm starting to investigate what will be required to lift my trailer. 2012 Jayco Jay sport 10. Currently has a 4 bolt hub on it. Any tire/wheels I am looking at or would want to go on Forest service roads all seem to have 5 bolt hubs. Are you able to swap out hubs or would I need to be looking at doing a full axle swap as well? I'm not against this as I could go to a beefier axle at the same time but if I don't need to that its a savings in cost. Thoughts or direction appreciated.
