Got my Answer via Lifeline Battery, Thanks

This is for those who have knowledge of how many HOUSE batteries in a Diesel Pusher Motorhome. I have to replace the house batteries in our DP in the very near future. I would like to go to Life-Time Gel Batteries. Current DP has 4 house batteries. If we replace our current DP with another DP in the future, I would like to exchange the house batteries between the DPs. I know this is possible if both have 4 batteries. Are there any/many Diesel Pusher Motorhomes that come from the factory with MORE than 4 house batteries? Or would it matter if more Life-Time Gel Batteries were added to the 4 year old group of batteries? I know it matters with std lead batteries but does it with the Gel batteries?

Thanks, rocmoc n AZ/Mexico

Forgot to add, 6 Volt Golf Cart Batteries!!!!!!!!!!!!!!
