The PD units are built as they are for a number of reasons. Most impotantly
is UL and RVIA listings for an application that can be demanding. While
regualr battery chargers can do the job on an intermittant bassis, an RV
charger has to with stand varoius input voltages, incorrect woring at many
campgrounds, Al types of weather including moisture inside the vehicle and
being powered up indefinatley. When connected to generators they have to
deal with electricla noise, being off frequency, and since it is also used
as a power supply, it may have to deliver full output indefinatley. And of
course it needs to do all this without strting a fire while someone is
sleeping.

The PD units offer a lot performance and the cost is not out of line like
some of the Marine offerings. It is an example of getting your money's
worth.

Also, keep the 100V wiring cord and plug. You need to have a service
disconect, line of sight in your control. That is why the Dometic fridge is
cord and plug.
