One Vs Two Batteries ?

Dealer is including one 12V deep cycle battery with my Rockwood 2703 order...My question is do I need two ? Or is one enough ? I don't really dry camp at all so that is not an issue.

If you don't boondock and you always hook up to shore power than your are ok. Your TV will charge your battery while you are driving also. We boondock a lot so we have a lot of battery on a lot of solar.

I agree with one if you don't camp without an electrical hookup, but see if you can get them to make it a Group 27 rather than a Group 24. We never camp without an electrical hookup either but one night the power went out at the campground and the Group 27 battery drained surprisingly fast. Of course the hybrid had incandescent bulbs that use a lot more power than the LEDs in new trailers today. The Group 27 will give you a little extra amp-hours when you need it.

I have 2 Trojan 6 V batteries. Wish I'd down that years ago. That setup will run anything.
At some point in time you will dry camp...

If always on power you only need one. But, if you ever dry camp you will need two, and you will need to monitor use so you aren't draining the batteries more than 50% of capacity. Make sure you fully recharge batteries after use, and keep them topped off. Don't count on the charge from the tow vehicle, plug em in and fully charge. Draining bats low means low life span and money replacing. Batteries can last for years with proper care.

If DW says we aren't camping without an electrical hookup, then we aren't camping without an electrical hookup!

I even asked the DW about getting a big enough generator to run the AC and anything else we want, but at a cost of over CDN$2600 for us, its just not a justifiable option for such rare usage. We rarely ever have a power outage of more than a few minutes at home so we don't even need it there.

No doubt Trojan batteries are top of the line but they're complete overkill for folks like us.

IMHO, sooner or later, planned or not, you WILL need that second battery....and a disconnect switch.
How many, many times have we heard about someone's batts going dead from parasitics or overnight furnace use, TV signal amp left on or having to stay at a rest stop with mechanical problems. None were planned, but they happened [me too]. There is no substitute for available amp hrs. Again, just my humble opinion. Plan for the worst, pray for the best. Cheap insurance. You can buy 110 amp hr deep cycle bats from Autozone for $115. Or in other words, you can get two for the price of one Trojan. Will they last as long? NO.
