Actually did some searching and found Dyers RV. A shade over $300.00 US, I don't know how they sell it that cheap. That's less than right from Progressive Industries.

Yeah I hear you Lucky Mike. I go through that a lot with aftermarket racing parts we sell. My supplier will not handle certain brands because the vendor will end up also selling to anyone off the street for the same price. They just look at it as "a sale is a sale" no matter who buys it.
On a side note does anyone have feedback on dealing with Dyers RV? I see they also have the large outdoor Dometic 72182 cooler that I find "went missing" in my DP when I went to pick it up after the purchase. They have a decent price on that also.

Don’t forget to purchase the little remote readout to place inside the coach - Very useful.  This is the best product you can buy to protect the electrics in your RV.  Good choice and worth whatever best price you can find.

 Yes the EMS HW50C
does come complete with the remote read-out.

Another Vote for Dyer's!  Their located a few miles from my house but they don't sell (out of their warehouse) to the locals.  We have to order it online like everyone else but I sure would love to save myself the shipping cost and just pick it up.

Dyer's has to have a really low price for us to purchase from them, we can sometimes get a better deal outside AZ since there's no sales tax.  Shop around.

We have bought from Dyers also, good prices, good service and communication, fast shipping.

if you have the access to wire between both I would do it...when generators start to de-tune power can fluctuate not to mention they can get stuck in high or idle wich can cause a brown out or overload in a hurry .......con against doing it is the small spikes put out by the genny can cause it to shut down alot......IMHO

 

There are two schools of thought on where to put the hardwired EMS in a rig: on the shore power input to the generator / shore power change over switch or on the output of the change over switch.  Cases can be made for both and neither is wrong.  I put mine on the shore power input to the switch. Here’s why:

If you get a spike or, as more lightly a “lightening hit” on the shore power the EMS will protect the change over switch and the co/ switch will still allow you to use the generator and even possibly still have shore power if the bypass relay in the EMS isn’t fried.  Also you don’t have to replace the changeover switch due to lightening damage.

If you lose the change over switch the generator is useless until you somehow replace or bypass the c/o switch. I’d like to still have generator power at night in the middle of or after an electrical storm if the lighting took out the EMS until I could deal with the EMS.

IMO, the odds of a quality Onan genset running wild is actually less, IMO, than a lighting strike in a campground. But, again, that's just how I do it and why I do it this way.  My version served me well after a particular event.

On edit I'll add: The likelihood of lightening related damage in a campground is increased significantly due to there being more electrical wires in the ground per square meter / yard then at a typical location; all those pedestals really close together.   All those wires are like big collectors of energy when a lightening bolt hits the ground or a tree in addition to a power pole.  They can just transfer all that energy to the power panels and then right into your rig even if everything is properly grounded. Again, that's why I recommend protecting the c/o switch and not worry as much about the generator going haywire.  Just my opinion but its based on many years in the electrical world.

Yes I think I will hard wire this unit between the shore power to transfer switch and NOT between the transfer switch and breaker panel. I don't have any doubts with the generator.....just the shore power.
Thanks for all the input.
