I have a 2002 Contessa that has no battery disconnect switch. I purchased the coach earlier this year and have since completed one 3500 mile trip with no electrical or mechanical issues. My previous fifth wheel had a disconnect switch that I would utilize for storage of the rig.
I have used the salesman switch in the same manner I used the disconnect switch on the previous rig. I reading posts on this forum I see opinions about not using the salesman switch for this purpose, some even saying to leave it on at all times. So far I have not experienced problems with the batteries. When I purchased the coach the house batteries were replaced with new but the chassis batteries were good enough to keep. Now to my question. Should I have a battery disconnect switch installed and if so, for just the house batteries or is one for the chassis batteries also a good idea? The coach has 110,000 miles and has functioned without a disconnect switch other than the salesman switch for all this time and miles. Your sage advise is most appreciated.
