2006 MADP 4140 - Couple of questions please

[Calgary-rv]

Hi Folks, I have a new to me 2006 MADP model 4140.


Have a few questions please:



1. Does this unit have electric holding tank heaters ? If so how are they activated ??


2. Other than the alternator charging the starting/chassis batteries when running is there anything that keeps a charge on them when on shore power ?


Thanks in advance

Since nobody with the same coach as yours answered, I'll tell you what my similar vintage Mountain Aire has. For the tank heaters, my 2005 4304 Mountain Aire has them. The switches are next to the sink outside the toilet room next to the shower. As for charging the battereis, my coach has a BIRD system that will charge the chassis batteries from the gen or from shore power. NOt sure if any of this is applicable to your coach, but I hope it helps. Best of luck to you with your new to you MADP.
