Help in proper heating during winter use

[Grampy]

I will be using my 2018 GrayHawk MPV this winter and have a few questions on keeping a water supply active during this time. Temps don't usually go below 20 and stay in the low 30's. Looks like everything underneath the coach is enclosed and only drain lines are exposed. I plan on using the water tank, not able to hook to city water. Each tank has a heater and i am skirting the RV with 1 1/2 insulation board.

Questions;
- is it ok to leave the hot water tank on the entire time, read where the tanks are only designed to heat up and not run like a house heater?
- Plan on using electric heaters, being the underbelly is enclosed does the coach heating system aid in keeping waterlines warm in non exposed areas? I don't plan on running the propane furnace.
- i plan on placing a 60 watt bulb in water pump and valve compartment under the master bed, should keep that area warm as well as the bottom of the bed exposed with the slid out.

Thanks in advance for your advice.

The one thing I would not do is use a light bulb for heat. There are several small heaters available with safety shutoff switches in case of tip over. We all have good intentions of being safe while keeping light bulbs safely away from items that will flame up, but there is just that one time we forget and disaster happens. My .02 worth.

Yes get a small TH controlled heater or heating blanket. Never use a light bulb for heating purpose.

I turn the HW heater on and leave it on while at a CG on full hookups. Works just like the one at the house on electricity. You can turn it off during the day or night to save the expense if desired as it heats up quickly.

The furnace heats the enclosed underbelly area so you may need to run it to avoid freezing the water lines when temps are falling. You could try using one of the trouble lights that "protects" the bulb with a protective cage and see how hot the cage gets before putting it under the bed.

One more thing - do a little reading on your fridge in colder temps. On cold nights, I'll add a 60watt bulb in the compartment to keep the fridge innards warm.
