We just bought a Transcend 26 RLS and I've got a couple questions that I forgot to ask the dealer.

Do the trailers come with 12 volt batteries ? If so, how many?

If it doesn't come with a battery, what type and how many should I buy?

Assuming, it comes with one, on average how long does it last?

I noticed that the trailer has a pre-wired plug for solar power. Can I assume that the plug is for a temporary solar panel who's primary role is to recharge the battery? What type and size panel would we need? Is anylhing else needed?

We are new to Rving so we won't be boon docking any time too soon, so the battery won't be over used. I'm just trying to familiarize myself with all this.
