Such a simple question requiring very complex answers.
Others have asked you to fill in the blanks.
Things we need to know:
~ What does solar mean to you? Trickle charge, boondocking without shore power, keep the rig's batteries topped off while stored?
~ Is your rig "solar ready"...not the same as the Zamp or Solar on the Side stuff meant to use suitcase portable panels. Solar ready usually means that you have built in connectors on the roof feeding #10 AWG wire routed to a marked location where you can install a solar charge controller, and a second set of #10 AWG wires leads to a connection to the battery bank. Both work, but each requires a VERY different answer. BTW, solar ready is worthless if you're going to do some mondo solar. Those #10 awg wires from the roof will be useless if you're feeding 800 watts of solar down the line.
~ What's your budget for solar and a good battery bank. Start at $1000 and go up for anything like worthwhile solar on a big, cushy trailer/fiver like yours.
So, as others have said, fess up. What do you REALLY want to know?
FYI, I have 400 watts of solar on the roof and 2 x 6 volt GC2 golf cart batteries on the tongue. We boondock exclusively. We are low-grade totally independent. With careful power use, we can boondock essentially indefinitely without shore power or relying on the generator for charging. We do use the generator for about 30 minutes total per day to run a microwave and espresso machine. We're not animals, after all!!
That's it unless it's cloudy/rainy weather that traps us inside. Then we run the genny because their ain't no sun.
Our system is minimal, and it lives in sunny Colorado at 8300 feet or higher. The sun is intense, and it's not filtered nearly as much as it is at sea level. I have the skin cancers to prove it.
Anyway, at sea level and in rainier climates, you'll need more of everything, including money, if you want to boondock.
If you're going to be a park queen...mostly using hookups...(not that there's anything wrong with that) your needs will be very different than if you intend to go off the beaten path and spend a week in the national forest with NO hookups.
Like I said, spill the beans. We can't help without that all-important info.
P.S. Dress up your signature and your profile info with all the pertinent info others need to know about you, your camping habits, your rig, your tow vehicle, and anything else that would help others answer your questions. Include models and years on both the RV and the TV. The "Classic" line covers a LOT of territory.
