I only have Progressive Industries power protection in my RVs. Progressive has both surge and power protection devices. Their power protection units protect against surges and a lot more.
I have the EMS-HW30C with remote display. This is a hard-wired unit that I don't have to plugin, worry about theft or leave behind. All Progressive Industries units have lifetime warranties.
