My First Camper Shell, Electrical help!

Hey guys,

I have just bought a snug top camper shell for my truck with the purpose of completely building it out right (the first time) and hitting the road. I am very skilled in carpentry, building, and making things move and work. Unfortunately, I am not skilled at all with electrical and solar systems which to me is the major part of this deal. I plan on installing two 100w mono panels on top running to either 3 95aH deep cell batteries. Also I want to install a 30 amp RV hookup for when I am camping in a park.

Any suggestions as in specific parts or brands you would use including amperage, voltage, watts ect. wiring diagrams, specific dos and donts would also be helpful. I really want to do this right and not just have it rigged up quick. I am very capable of doing this myself with a little instruction. I am open to all ideas.

Here is everything I want to accomplish.
I want to be able to charge my batteries with the trucks alternator when the truck is running, (I'm guessing a continuous duty solenoid?) yet when my truck is turned off I want the solar panels to kick in and start charging but as soon as the batteries are done charging I would like for the whole system to shut off (charge controller?). Also would be nice to manually shut down the system completely to run power off of the RV hookup. I want the RV hookup to run directly to the outlets safely if possible.
I really want to prolong battery life, thats why I want to be able to shut down and turn on the system manually, If i can run deep discharges above 30% then back to full instead of a bunch of small discharges to say 70-90% back to full charge would this accomplish a prolonged battery life? or the option of discharging one battery at a time or two or three. I know boats use a switch that allows that option of battery 1, 2 or both. can this be applied and is it viable?

Also let me know if the solar system listed above is overkill or under. I am a minimalist so i only plan on running my computer for school work, a small fan, or ceramic heater depending on the season, and some small led lights or a small lamp. maybe a small electric stove in the mornings.

Thanks in advance guys.

 

Welcome to TW!
Not many look in the new member forum to answer questions.
It sounds like a cool project, maybe if you ask it in what Generation truck you own (1GEN, 2GEN, 3GEN)
truck discussion sections, you will get someone to chime in.
There are very skilled people here who are very smart who can help.
Good luck. Happy trails....
