You didn't make any mistake getting the PD converter. It will do its work with ease and also extend the life of your batteries. The Elixir, as well as WFCO converters, are junk. I replaced the WFCO converter in our Jayco with a Boondocker and our cousin replaced the Elixir in his Towlite with a Boondocker as well. Both the PD and the Boondockers have similar operational results. We used what we did because they were a direct replacement to the OEM in the trailers.
