I am about to buy my first 5th wheeler. Have a question about the supply of power to the rig. There is a 40 amp supply to the rig, is it direct from the battery? If so, will this drain my truck's batt...

The electric current hook up is going to be either 30 or 50 amp. The plug on the end of the cord is different and you can buy adapters to connect 50 to 30 or to 20, etc. Your tow vehicle (TV) must be running or have the key on to supply power to the RV battery. While running, the alternator provides charging to the RV without draining the TV battery. With just the key on, you could drain the TV battery and that is not recommended.
Your RV battery charges while plugged into AC at the campground or at your home, or while driving down the road. If you camp without hookups, you need to be energy conscious or have solar and/or generator to replenish the battery. Also when camping without hookups, you can only use the 12v items like most lights, furnace, landing gear, etc, but not AC, microwave or television unless you have a special setup like a large battery bank with lots of solar and an inverter.
The amps you mentioned are only supplied by an electric outlet connection. You fiver will have a charger/converter that charges the batteries and converts 120AC to 12v DC when plugged in to the electric outlet. Otherwise, the 12v DC is provided by your battery bank.
