Forest River for whatever reason. Some of the later model pods have been pre wired for the Zamp system, but I am not very familiar with them. Apparently they are similar to the Renogy portable system and you can plug the Zamp panels directly into the pod power system in the pre-wired power inlet port.

I recently installed a Renogy suitcase 100watt system for our pod. I modified their system a little , but the standard system has battery clamps that attach directly to the panels. The charge controller is attached to the panels.

I expect that the panels will keep our batteries charged. We have 2 6 volt golf cart batteries and 230amp hours . We have learned to conserve power and hope to be able to last 6 days without moving our campsite. I posted an article about our system earlier this week in the pod mod section of the forum.

I installed a 100 watt solar panel on my sailboat 6 years ago and never have used the battery charger since.

Whether a single 100 watt panel is sufficient for you is greatly dependent on how much power you use in a day.

If we're talking about summer months, on a bright sunny day, you'll get about 5-6 mean solar hours of output from your panel if you keep it angled fairly well to the sun throughout the day.  That means 500-600 watt hours of power.  If that power is strictly be used to recharge your batteries, most of which will, you will lose 25% due to the heat created in the charging process.  That leaves you with 375-450 watt hours of power available to you in your battery (~30-38 amp hours in 12 volt terms).

Generally speaking, that's enough to run your Fantastic Fan for several hours each day, your electronic panel on your refrigerator, your propane detector, and your water pump for a fair amount of time (mine draws 7.5 amps when running).  I also charge our phones from our Pod's batteries, but this consumes too little power to even factor in.

I've noticed that the furnace draws quite a bit of power, especially when outside temps dip below 50F and we keep it about 70F inside.  I would estimate that on such nights (no day use), the furnace probably consumes 20 amp hours on its own.

So if you aren't running much more than that, a single 100 watt panel will probably work well for you assuming that you're getting a lot of sunny days.  Solar panels don't work well on cloudy days; their output can easily drop by 50-90%.  On rainy days, they're practically worthless.  For those times, you'll either need to run your generator to recharge your batteries or else get an inverter for your vehicle that can do the same thing (your vehicle must be running for this much of a load).  The latter option is far too often overlooked by folks.

Edit: Just found a thread where they did this. Looks like it should work.

You are 100% correct in that any power you don't immediately consume from your panels will go into your batteries.

Whether a 100 watt panel will fulfill your electrical needs depends on what you're running.
