Furnace while boondocking.
For a 33' travel trailer, how much battery usage can I expect from the furnace? They are calling for low 40s over night and the women like it warm. The only site left was no electric so I booked it....

A marine/deep cycle battery is a hybrid battery. It does either starting duty or house duty. It does neither well.
That's a blanket statement that like most generalizations, isn't always accurate. Marine batteries are available in starting, hybrid and true deep cycle. Yes, the marine "deep cycle" batteries at Walmart and Costco are hybrids, but true deep cycle marine batteries are also available.
