Leaving hot water tank turned on
This past weekend, we left our hot water tank turned on all weekend. Our old TT just had a gas hot water tank but the new one has both gas/electric. Was much easier to leave the electric element on in...

One thing that has not been discussed is the total current drawn when using the WH on electric while the A/C is running on a TT 30 amp service. That's my situation in the Florida summer.
The manufacturer's electric specs are:
Suburban 6 gal with electric element draws 12 amps @ 120 volts.
Dometic Brisk II 15K BTU A/C draws 13.2 amps on the compressor and 2.7 amps on the fan all @ 120 volts.
My WFCO 55 amp converter normally draws 5 amps with a few lights on.
All these amp ratings are with 120 volts. In most cases, campground power will be much lower which will increase the amp draw.
If you do the math, the total amps with the WH electric element on and the A/C running @ 120 volts is 12 +13.2 +2.7 +5 = 32.9 amps. The main breaker will start heating up and will trip if the campground service breaker doesn't trip first.
I do use the WH on electric but only at night when the A/C is not running as much.
