My Jayco 28.5RLS came with a PD4045. While it is a 3 stage charger, it does not allow you to manually select a charging mode which is a drawback when boon docking and you have a limited amount of time or gasoline to recharge your battery. If your battery is only partially discharged, the PD4045 will likely choose to recharge at 13.6 volts but you might prefer to recharge at 14.4 volts to quickly recharge your battery.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
