Had one on the other 30 amp coach and it paid for itself the second time used. CG pedestal was wired wrong (open ground, open neutral). Surge protector wouldn't allow a connection to our coach.
Just ordered the Progressive Industry EMS-PT50C for our new coach before our upcoming trip in a couple weeks.
Wouldn't own a coach without one.
