Add to that you have the option of buying US made or made in China.

Hmmm, tough choice... :) It's an um, an anomaly! :B

It's fixed at 136" ... i.e. 2 minutes, 16 seconds. I've actually timed my own EMS-HW30C and it's two delay settings are indeed 15" and 136", accurate to within a second.

Did not know the Portables were pre-set to 136 Thanks. Will modify in the futuree

I still recommend the longer delay time because I do use Air Conditioners

Though I agree 15 seconds is long enough to analyze... There are also some other considerations.. 15 should cover them too but I'm not so sure

(When power is restored there is a bit of a roller coaster ride for a few seconds, I'd like to think just a few (liek 5) but .. Well. I've never timed it).

Progressive Industries. Buy the best you can.
It could save you $$$. Never know when a fault will occur. I've seen underground faults in an Rv park that wiped out all of their units electrical stuff.

Should we really use one for our 30 amp service and if so what is the best ones to get?

There's some useful suggestions on the subject in the first two pages of this recent thread but unfortunately starting on Page 3 it just went into the toilet. :R

If your Rv is a 30 amp then the Progressive Industries
HW-30c is the best, hard wired in so you do not forget it. The Portable version (PT-30C?) is the alternative, in both cases set the power on delay to LONG, this is important (it ships set for Short).

Delay for the Progressive Industries portable EMS-PT30C and EMS-PT50C is fixed at 136" and cannot be changed to 15" as can the hard wire versions EMS-HW30C and EMS-HW50C. I run the short delay most of the time with my own EMS-HW30C as I don't use A/C often and 15" is plenty of time for the unit to analyze incoming source power and decide if it's acceptable.
