Met an RV'er in my RV park who pleaded with me to purchase my Lamda power supply. Boy was he mad. I asked him to check the make of his onverter.
"It says W.F.C.O.
Should read WTF Company"
Since he was headed home I convinced him to simply drive eight hours a day and let the alternator do the recharging. Checked the charging system and the alternator and wire distribution system was broken. Busy weekend. I connected him to a 300lb power supply on a dolly. That one put me to work for three days. God I hate working on Class C motorhomes.
