LATEST PROJECT - Truck Drawers/Sleeping Platform

[TheJosh]

Great build!

I've recently decided to go the heat exchanger route vs a propane water heater. But I heard that water that goes though a heat exchanger is not potable, is this true?

I guess it depends on the materials.
They make heat exchangers for brewing beer, you know? I guess it's OK for potable beer but maybe not for potable water???
IDK.

The stainless heat exchangers are made for potable water. They have 4 ports. 2 ports for potable water (feed and return) and 2 ports for the hydronic fluid (feed and return) That fluid could be water, water and a bit of antifreeze (from vehicle). The 2 fluids never mix together. It is always seperated by a plate. Very effective. I've used them on many heat systems and whole house on demand hot water systems.

TimS answered exactly as I would have. No issues with using the PROPER heat exchanger. Just be sure to do your research.

Sir you have inspired me to make a system similar to your for my Tacoma! I have been drawing plans up for days now with the inspiration from your sett up. Going to Home Depot tomorrow to see what kind of a dent in my wallet with will have!

I really like this idea, but it seems that substituting rectangular tubing may be an improvement. .5" x 1" aligned vertically provides the same strength in the vertical axis, narrows the assembly by 1" per drawer, and provides shorter mounting bolts to the drawers. It could even be increased to .5" x 1.5" if one wished to make it stronger (such as the slides). Great thinking 'out of the box'.

Waldo64: All very good points, however I could not find a way to stack the necessary bearings and bolts into a 1/2" space. I managed to make it work on the outside slides, but couldn't find a solution to the central support between the two drawers. After using it as is for several years now, I feel strongly that the plywood would tear out well before the strength of the slide was maxed out. After this much constant use and countless miles of extremely rough driving, I have no complaints with how this has worked out. Who knows, I may need to start work on version 2.0, but its hard to find enough issue with the first version!

some lovely work there, with some great ideas

any chance you can part pics of how the drawers slide on the rollers...
do the drawers have metal channels where the slides roll on?

thanks for posting great thread..

Can't really take any better pictures than what is shown in post #43. Here's a link ... click here.

Of course, let me know if you have any other questions!
