Generator On Rv

If you are not in a park do you run your RV off of a generator ?
We are thinking about getting a RV & wonder if we stop somewhere instead of in a camping park can you run an RV off a generator for the lights & TV ?
Yes you can. Perhaps you will only need to run if for an hour or two. The down side is it uses fuel and makes noise. Usually you run the generator for the big things: air conditioner, electric cooking tools, electric hot water tank, or a normal tv. Most campers are set up so that everything (all the lights and water pump) will run off of battery power or LP gas. The refrigerator works off LP gas or electric (some will run off battery power, too). Small tvs can run off 12v. Inverters can take battery electricity (12 v dc) and convert it to 120 v ac for short use of some electrical equipment.
Ultimately, you can use the generator to re-charge your batteries.
Some people try to be "pure" and not run the generator unless they really need it. Others run them all the time. Your choice.

What Size Charge Controller for Generator--->RV Battery?
I recently bought a cabin with no power connection. I am planning on a 2000w generator--->charge controller--->RV Battery--->inverter. (I will add solar a bit later.) Seems sensible to add a battery, rather than having a generator running all the time.
I'm clear on the generator and the inverter, but I am not understanding what size charge controller I need. I was planning on a DieHard 12v RV battery - reserve capacity 200 min, 115 amp hours at 20 hour rate. The charge controllers I am seeing are as small as 7 amps and up to 30 amps (and seem to be intended for solar, rather than a generator charge).
How do I choose what charge controller I need for this battery and generator?
Charge controllers that are meant for Solar charging are significantly different to Battery Chargers meant to be used on AC. I suggest using an Automatic battery charger and adding a Solar charger controller at a later date.
Since you won't want to be running your generator for many hours, get a reasonably beefy one. e.g. if you were to base the charge rate on the C/20 rate your 115 A/h battery would take 20 hours to charge at 5.7 Amps (+ a bit to allow for conversion efficiency) (assuming full discharge, which you don't want).
