Brought the Sea Breeze home...but have a question

So the Sea Breeze drives really well. I was impressed for a 1995. I had driven it before buying but this was an actual trip and the results were very good. The 7.4L TBI did a great job and only kicked down on the bigger climbs. Never went lower than 3rd and didn’t have to stay there long. The engine is so strong in this thing…I was worried because it isn’t the Vortec but it has more than enough get up and go.

I do want to install a tach just to monitor what the engine is doing, but other than that I think she is good to go. We burned just over an eight of a tank of gas traveling roughly 90 miles in the rolling hills of southeast Missouri into Illinois. I haven’t even started figuring mileage yet but that seemed pretty reasonable for a ten thousand pound RV. I am figuring probably 7 or 8 MPGs, which is what the previous owner reported. Seems about standard for a gasser.

One question: In motor homes, are their two battery systems? Like is there a standard battery for the engine and then a deep cell attached to the inverter for the 12 volt systems? That is pretty much the only thing I don’t know. I haven’t seen a second battery but I am thinking that there is….?
Anyway, really pleased with the purchase! Motor homes are really cool!
