so i had a longer post but it logged me out and only saved about half of it.....
So i'm bored, deployed and with a little bit of time on my hands for a change. Before i left i had just started my build on my 03 f250 ccsb:
http://www.expeditionportal.com/forum/threads/113795-03-super-duty-build
i'm looking to add 20 gallons of water, with a pump and another 4 gallon tank with a water heater to give me flowing water for either dishes or a shower. i'd like to add a similar setup to the dual batter system shown here

and on the roof rack of the truck i'd like to add the RTT with solar panels over it, check my build i explain everything there.
now, after hours of research its apparent that there is not really a good solution to heat the water with electricity, i'm going to try though:ylsmoke: my thought however was to use it as a dump load for the solar, solar doesnt need one like hydro or wind but if there is extra mine as well use it. first store the water in a really well insulated tank, i was thinking of a vaccuum tank similar to a thermos but it i cant seem to find anything like that for sale, options welcomed. as its looking i'll be able to fit 6 up to 9 of these solar panels on the truck i'll probably end up putting 6 on there to fill up the space i've set aside.

it seems like each is rated at around 100w of power giving me 600-900w of energy, i'm going to be powering other things but i think most of this will be excess power so a good dump load makes sense i think. my idea or plan or thought was that while driving to the destination the alternator charges the batteries then heats the water with the excess energy, this would proably have to be limited to not burnout the alternator. so i'd have about 4 gallons of hot water, hot enough to need to mix for a shower or dishes, so that i'd only ever be heating maybe 30 degrees instead of from cold and having to raise it 50 + degrees or so. i'd also like some sort of temp shutoff.
i was thinking about these as charge controllers

and something like this for a heating element

maybe 2 in parallel if i'm reading it right. thoughts? would this work? i know there are some solar gurus out there and obviously there needs to be more math done but i think i can safely say a majority of the power will be excess. and lets assume while parked 2 hours during peak hours(4?) would be devoted to just heating water, thats 1200w of energy to heat the water, i'm thinking it should get hot and stay hot till later that night when its nice to have a shower.
