Adding a second battery?
My new to me TT has a 12V Interstate deep cycle marine/rv battery, spm-24. Looked on line and it offers 140 min. at 25A and it looks like I'm could use as much as 10 amps an hour without the furnace ...

I have 6-6 volt batteries in my boat (trawler) as a house bank. You do get more power out of a pair of 6-volts vs one 12 volt battery but I believe the best thing about them is that they are TRUE deep cycle batteries and can be discharged repeatedly (no more then 50% is recommended) and then recharged many more times then most any of the commonly available 12 volt RV house batteries that are available at Walmart, etc. Trojans are always rated very high, but they are not cheap. I got my 6 volts from Sams; Costco also has them at a good price. I have 'heard' that if you want Trojans, then try to find a distributor who supplys golf cart businesses (OK, I'm in Florida) and you may be able to get better pricing.
