Your battery was probably nearly dead before you left for camping unless you charged it the night before you left. Trickle charge from the truck will barely charge it if it's dead.
Until recently a battery disconnect was not standard on any camper and not on the Roos. This means your radio and LP detector were siphoning power from the battery continuously at a rate of 0.15 amps. Tiny draw but that adds up to 25 amp hours a week! Since an indifferently maintained Group 80 battery really only supplies about 55 useful amp hours letting the trailer sit for a couple of weeks will pull the battery way down. An hour or two drive won't put much back.
Install a battery cutoff. Any boat shop will have a single -- On/Off -- battery switch that's weatherproof. Install it on the Negative (Ground) wire to cut all power from the battery to the trailer. Charge the battery overnight before your next camping trip, too.
