If I had to replace today, my choices would be in this order 1) Endurance by Goodyear, 2) Radial Trail HD by Carlisle, 3) M8008 by Maxxis.
Biggest draw back to the Endurance is lack of a long track record. But they've been on trailers since early part of 2017. If there were many short term problems, the RV forums would be overheated by now.
The Carlisle's have been out a year or two longer than the Endurance. If this new design tire was having the same problems the old style Carlisles were, the RV forums would again be overheating from the posts.
