Trailer Fridge on Battery while towing?

[JeanE]

With my 2008 RX400h, I tow a travel trailer.  Would it drain the Lexus battery to leave fridge on the "battery" setting while I'm towing, meaning the trailer battery is being charged by the Lexus battery.  Opinions?   Thanks

Isn't doing that a common practice - at least on non-hybrid vehicles?  I assume your RX400h isn't spending much time in EV mode when towing your travel trailer so I would think that the alternator is running most of the time and would charge your RX battery and power your fridge OK.  You would likely find lots more information about this on RV forums.

JE;  I was told that Towing a Trailer w/an RX 400h would burn out the Motor, that U hafta have a Gas Engine so that won't happen.  I'm curious 2 know of your exp. 'cause I'd like 2 get a 2,000 # or less Teardrop Trailer but figure that I'd hafta get another RX (Gas) or the new NX.  Pls. keep me posted.  Thx.
