Wild – looking forward to reading how the heater turned out for you and if you’re able to get your water temp >110?  Your trailer is coming along very nicely and is impressive.  That whole sink thing would of drove me up the wall – looks like an octopus, lol.  Grats.

I got my car stereo/mp3 player finally hooked-up and ready to go.  Bought some enclosed 4″ box speakers for it – there’s no bass but having some music in there is pretty nice. Definitely recommend it for your 12v set-up.
