That's a good topic to chew on for DIY water heating systems.
Temp regulation for the shower is a trick I'll need to learn.
My 1st plumbing was complicated (performed to residential code, cause you know I’m basically nuts). I had shut of valves & drain lines & exterior hose bib, brass risers from the HWT.

2nd time around I went as basic as possible. (See photo above post)

This time my hot water side consists of the “Pex“ fitting into the tank, the pipe (about 15” long), & a “Pex” fitting at the end where the tap screws onto.

The cold side is; male fitting to accept flex hose from the 12v pump, a T, a fitting to the cold side of the faucet, a short pipe to the fitting into the hot water tank ( cold supply ).

Pressure relieve valve is piped thru the van floor to the outside.

Thats a great economical solution.
Thanks MesaAZGuy

Yes & the install was way less fitting & no valves / hardware, compared to my 1st install (Titan 4 gal tank).

sometimes I try to maximize on all parameters & choose the wrong thing (this was the case with the Titan). This time around I have less hot water capacity 2.5 gals, but all I have is a sink so Im guessing it will work out ok.

If I do a van #2 at some point, I think I will gravitate towards simpler what I did in van #1. Also I would economize my systems & space more (ie house batteries being the drivers seat not under the rear bed). Design & the thought of is huge. We also have no RV experience as adults until last year, so we are quick learners of what works well for us & what doesn’t. So far we are very happy with the Promaster.

I like the learning we have done & the easy adventure the van provides us. We did not “nail it”, but got pretty close with our 1st prototype. The items we got wrong we will swap out (like this hot water heater & $300 error on my part). That is the cost of an education

If I wanted hot water for just the sink:
I have seen 12 volt elements for some of these too. 1.5 gallon generally. Plenty for dishes, etc. No mixing valve for hair washing though.
Thanks RD

I would be interested in the 12V depending upon the specs of the battery consumption etc.

I have not road tested the Rheem tank install yet, but I’m quite happy with the “driveway” performance I have tested.

I’m pondering of a system to supply the 120V for 15minutes while driving to utilize the PM alternator via inverter to heat up the 2.5 gals. The idea is the inverter would be switched on 15mins before stopping. I guestimate that process uses about 30 AHRs @ 14volts

I also have a Honda generator I can plug into my shore power for 15mins if need be.

I expect the charge while driving will work great and give you all the hot water you need and full batteries. Consider remote easy to access switches for the inverter and hot water heater.

Propane Locker

I decided to built my propane locker out of 22GA Sheet Metal. It is designed custom size 13.75” x 13.75” x 20” high. It has a door on the front for access (slide the 20lb tank & milk crate inside). The wood floor will be used as I have mounting flanges at the base of sides (Screwed & caulked to the floor). I will have to locate an area to drill and mount am exhaust pipe thru the floor inside the locker to let any leaking propane escape.\

A Bed Mattress;

On another note one of our choices was a queen size memory foam mattress cut down to 74 inches from 80 inches length so it could fit between the walls. We like this mattress so much we bought one for our cabin.

for us it was extremely comfortable and being all foam, you can unzip the fabric covering cut the foam and zipped the fabric back up. There’s a trick to unlocking the zipper that you have to know which is using a paperclip

Hi RV8R, When you unzipped the mattress to cut it, was there any fiberglass that escaped? I am looking for an 8 inch mattress to cut but most have fiberglass added as a flame retardant.
Thanks,
Opus

A Short Queen was the perfect size for my bed build - no need for cutting. And now our van mattress is much more comfortable than our old Ikea mattress in the house...all the more reasons to take trips. (We went with the Lucid 10" gel memory foam mattress sold on Amazon)

Hi,
Nice job on the propane locker.

One thing I wish I had done on my propane locker is to make it large enough so that I could fit a couple of the tall 1 lb disposable propane cylinders in the corners of the locker -- it just takes a fraction of an inch more that the minimum needed for the 20 lb cylinder. I carry a couple of the disposable 1lb cylinders and an adapter that lets them plug into the regulator I use with the 20 lb cylinder -- this just in case I miscalculate on how much propane is left and run out. Looks like your locker might have enough room in the corners for the 1 lb cylinders without the plastic case.
Another thing I wish I had done is to allow enough extra vertical height to allow for one of the propane gauges that sit under the tank and report the weight -- the only way to get an accurate reading on how much is remaining. I use one of these: Amazon.com : Grill Gauge Original Propane Tank Scale for BBQ Grill, Patio Heater, RV Camper - Improved Design with Easy Lift Indicator - Works on Standard 15/20 lb Labelled Exchange Tanks : Garden & Outdoor
and it works fine, but I have to open the locker to use it.

I had the same problem when I decided to use the TankCheck transmitter that goes on the bottom so I used a router on the wooden lid where it made contact to give me the 3/8" space needed. The TankCheck does some sort of radar/sonar trick to figure out the amount left and connects with your phone via bluetooth

Hi Opus

No, no fiberglass, just foam & memory foam

There is a slight trick to get the zipper open, had to use a paper clip

Good to know about the 1lb cylinders. I‘m still working out the smaller details, but I’m getting there.

Hey mcneill78

Is that the same one that is posted in the Gadget thread?

“Mopeka” brand?

If it is a different brand, could you post it the “GADGET” thread with any report of easy of use etc?

Below is a snapshot of the World Trekker report

It is a gadget that is on my list, as iPhones & iPads have become gadgets of my life (ever since the Apple iTouch came out “before iPhones & I realized we could pack a pocket internet computer on out motorcycle road trips & hook up to Starbucks“. I’m a bit of a nerd I guess.

The Mopeka is the TankCheck, occasionally get a false full or false empty but ten minutes later it reads correct. I asked if this could possibly be used to measure water tanks and the company thought it would work. The TankCheck has several tank options and maybe one of them would work with a water tank.
