Pretty much. Just one caution... The retaining pin on early units was weak and occasionally allowed the tube to drop down while towing. I think that defect was corrected, but I know some people rigged up a fail-safe.
It’s the same with swing-away jacks. Many people bungee them to the frame to prevent them from accidentally swinging down while towing.
However, I am recalling that new 13’ers now sit about 3” higher, thanks to a different
axle spec. Wondering if the regular tongue jack might be fine now. Maybe wait and see?
