I've never heard of that before!! I'm not sure I would trust them pulling a trailer. Just my 2 cents (keep the change)

My last truck was a 1988 GMC 3500. 5.7L 3 speed manual.
every single morning when I went to stop, the rear drums locked up something furious! It probably woke up all the neighbors!
everything was is excellent working order...but thats just the way it was. Granted that truck was made 21 years ago....technology has come a ways..
lol
