You'll be much happier and safer with a good battery. A cheap G24 deep cycle isn't much money. You need it for the brakes, as noted. Also, many converters put out a lot of ripple on the DC. The battery helps smooth it out. It will also help prevent the lights from flickering so much when something like the pump or furnace kicks on.
As others have said, you would be best of having a working battery.
Besides the brakes, you might want to stop for lunch in route and it would be nice to: open the slide(s), have the water pump, turn on the radio and/or interior lights, and have the refrigerator running..... without leaving your tow vehicle running.
Have a great trip whichever you decide to do,
I plugged into 110 and turned my fridge on, without the battery connected, one time and blew an obcured 5 amp fuse in the fridge. The fuse was hard to find because it was inside an electrical box as opposed to another fuse (was ok) open to view with the outside fridge access panel off.
I don't know if the lack of battery ballast caused a power surge but suspect so. I think the inverter expects a load not only for controling ripple, but spikes that may occur when turning various devices on and off.
Days spent camping are not subtracted from one's total.

Thanks for all the input. The battery went dead after my last dry camping trip and I had it for 4 years and 10 months. I just checked my Costco and they have a g27 for $83.99. Much better than the OEM one at $250.00. Thanks for all the input and advice.
