What's an ultra kit? I bought this and I think they call it an upgrade.
http://www.bestconverter.com/4600-series-Upgrade-Kits_c_133.htmlI also looked at PM and PM chargers. They seem to have a good reputation.
It's been a while now so it's foggy and I'm glad to be past the converter stage of trying to be my own power company. :)
the wfco that I had for a couple minutes would never go past 13.6 v, the 30 amp reverse polarity fuses were so loose that it would quit charging until I reached in and held pressure on them. While trying to trouble shoot it I felt for other loose items and was shocked on the exposed terminals of the 120 power cord.
