Problem with battery. Experience guy needed

Hi,

As you know i am new to RV
My toy hauler came with a cumins 5500w generator.

On our past two dry camping adventure we experienced dead battery.

We only use the batteries for light, water pump and furnace fan.
I am not surprised to use all the batteries with furnace pump and light but i am surprised that a 3 hour drive (hookup to the TV) and then 2 hours run of generator is not enough to recharge the batteries.

My dealer is telling me that those deep cycle batteries needed at least 24 hours hookup to recharge the batteries

I don t get it?

Also if i buy a solar panels kit is a 100W kit enough?

Thanks

TV will NOT adequately charge trailer batteries.

You need a 1000W MSW inverter and a good "smart" battery charger. Voltage drop/loss from the TV to the trailer will be to high to adequate charge the battery.

Even with the inverter you'll need to be sure the voltage supplied to the trailer is above 11 volts with FULL charging load.

Revision: use the inverter for powering the PD while underway.

Make SURE you have low resistance wiring, positive + ground, between the PD and the battery.
