Don't think many people would shell out the extra $$$ for them, especially on a trailer with a 14,000# GVWR.
I know they are not cheap - mainly a safety/maintenance/comfort issue.
Kodiak brakes can be installed on a 320RS for approx. $2000. or less.
Mor/ryde in Elkhart, IN has installed quite a few of these for various RV companies.
I guess it depends on where you will be traveling off/on & for how long you plan on keeping your current model 5er.
