I really like what your doing with your suburban, especially the multi-use mobile living/house setup. Reading through your posts, I noticed the mention of the heat exchanger/hot water pump system in your misc mods on your truck, from the beginning of the thread. As you suggested, would you mind doing a write up or explaining how you put it together?
Hey jcoov1104.
This past weekend I just redid the whole heat exchanger shower setup, and it is much, much better. My pump was being eaten up by the engine bay heat. I fit the pump, filter and mixing valves into a 18" harbor freight toolbox with quick disconnects for the heating loop. Uses a five gallon bucket as a "tank" and also an additional fountain pump to bring water from a river/ lake up to 75ft away. Everything fits in the bucket and the tool chest. I'll get pictures when i go camping next and post all the details. I have one or two improvements I want to make before making it "final"
I also recently added some curtains in the back. I took curtain material and think Mylar (thick enough to not crinkle or make too much sound). I sewed the mylar to the exterior of the curtain material and sewed a 1/4 inch metal rod between and then glued some high quality magnets on the window. A few weeks now and it works perfect. I am not sure if these curtains or the paint makes the biggest difference, but I can now sleep in to 1030-11 even in direct sunlight before having to open some windows and turn on some fans.

The cruise control downshift points are actually different than the normal shift table, making it downshift easier (or harder) is very easy.
