The new WFCO's any good ?
Asking for a friend.... I know in the past they basically suck. Mine in an old MH used to eat batteries... This one in his new TT is a WF-8735-P. It "says" it's a 3 stage charger, but these things hav...

35 amps is ridiculously low amps wrt to a two-battery or more bank for any generator powered charging times as was stated above.
On WFCO's, you do have to check the actual situation. They only go into boost if AFTER they start up, the spike in battery voltage stays under 13.2 volts as seen at the WFCO (miles away on long thin wire and the high R for that.)
So that means before you start the WFCO the batts have to be at say 12v so they don't spike over 13.2. That in turn, depends on how many amps that WFCO will hit them with vs how big is the bank in AH.
The bigger the bank and the lower the initial amps, the lower the voltage the spike will be at 50% down SOC. So with a 35 amp WFCO, and two batts, that will not be so much of a problem as a 55 amper would be on one batt for the same wiring job.
time2roll is always going on about just reducing your 55 to a 35 if you want to ever see 14.4v. You see why by reading the above.
A friend has a Cardinal 5er with a WFCO that does 14.4 no sweat. That is because it is mounted by the door-way just into the front cargo bay not far from the batteries. So there is nothing wrong with WFCOs as such. You just have to know what the drill is with them, and act accordingly.
