Thanks for all of your help I ordered the 80 amp from Adventure as I do have a 20 amp circuit

Get the 80 amp and they have them on sale at adventure rv

The answer actually depends more on your batteries and your isolator

For a pair of GC-2 with bi-direwctional isolator (Motor home only) 80
For Group 31 pair in parallel Go with 80
For group xx less than 31 (2 in parallel) go with 70

How to decide on your own.
Find battery 20 hour amp hour rating (C/20 rating) NOTE: Wal*Mart does not use this rating so look it up on say Interstate or US-Battery .. Make really does not make much difference, SIZE does, also cranking amp;s are not important only 20 hour amp hour rate or as close as you can get

Group 24 73 amp hour
Group 27 and 27 Just a bit under, and over 100
Group 31 `
GC2- Pairs or 4S (12 volt) 220 give or take 10.

Now total your amp hours.. Multiply C/20 capacity by 0.30 and that is the size of converter you want, or close to it.

Source: Xantrex.. NOTE: This applies to flooded wet not AGM (Go big on ABM)

Note 2: Using that formula with brand new GC-2's I found I did not need water often,,,, I upped the battery size some over the last decade and my new DEKA G-20s have gone over `8 months without asking for water.

Most RVs will run fine on one battery and 30 amp converter.
45, 60, 70, 80 only matters if you think it does.

I'd play it safe,... go w/ the 70 amp. You can bet it will put out more amp hrs than you ever saw from that Wfco. And why would we haggle over 10 amps anyway ? After 10 minutes of charging, you'd be haggling over about 2 or 3 amps.

+1 Just going with P.D. is a huge upgrade

You might get better answers if you tell us a little about it's use. For example, what is your battery bank, what kind of RV you have, and any other pertinent details.

Methinks it may depend on whether you boondock or not. Lots of lead in the pencil and nobody to write to is IMHO a waste of money.

Check the specs between the 70 and 80 if you have a 15a circuit. The 80 requires a 20a circuit, don't know about the 70 or what the WFCO had.
