Solar panel with 6v batteries?
My 5th wheel has a 90 watt solar panel on it with a PVCM25D controller. The two 12v Interstate batteries that are in it have died after 5 years and I need to replace them. I'm thinking about doing two...

As 3tons mentioned, 6 volt batteries are taller so expect to have to expend some effort coming up with a new holddown scheme. With our Winnebago, when we changed over to a pair of 6 volts, I finally went to a golf cart dealer who fixed me up with a hold down that ran across the long edge of the battery and was made for hold down rods that ran at a 45 down to the tray on the other side of the battery. This only worked for me because our battery tray had a lip the new hold downs held that batteries against. The original 12 volts had a flat top that a bar ran across with hold down rods on each side. The 6 volts with their caps and terminals did not have a clear shot across the top for the original type hold downs. Nothing is ever easy on RVs!
