I have a 1993 Safari 34 foot house the think it’s called the Oshkosh chassis it has what appears to be six lug wheels 19.5 is there a source to buy one new or used for a spare wheel

If you want new, any heavy truck parts outfit should be able to source on for you, as it is a common item. Used could be had at any truck/bus scrap yard or even on craigslist.
