Rockwood tent trailer (model 2318G) has no power

Question edited for clarity.
Question moved to RVs.

It shouldn't do unless the controlling software is faulty. There should be a diode that only lets electricity flow from the solar panel to the battery in sunlight, but shouldn't allow electricity to flow back to the solar panel at night.

Batteries should last 4 to 6 years if they are looked after, and during the winter months, they should be on a battery minder to keep them trickle charged.

Any electrical items in the trailer tent like fridges, microwaves, televisions, heaters, AC etc, may be drawing some power when not in use either by design (standby) or by error (parasitic draw).

Request the manual from Rockwood.

Call ur local dealer

Forest River manual for your travel trailer says they have hydraulic and electric slides. Look online for the manual for your slide manufacturer for troubleshooting steps.

Should be a fuse or breaker somewhere between the lights and the power source.

Tent World........

Check for a faulty inline fuse or circuit breaker at harness attached at front of trailer. Follow positive wire back to trailer.

you may have to prime the pump to get it to start pumping

check connections -test and check ignition ,gas valve ,thermocouple for proper placement ,dirty or damaged
