To add to your note, Sunline in at least the year 2,000 and newer had a mixture of Alko, Dexter and then Lippert axles. Dexter was the only one I have seen on the smaller, 3,500# and lower axles with the push on cap to hold the nut from turning. The 5,200# and larger axles I have seen are cotter pin. I do not know this is a fact on all larger axles, just many I have seen.
Good for you son Jerry. Glad he is now among us camper owner folks.
