    I'd like to have hot water at the sink but I don't want to go with a water heater. Any reason i couldn't use an instant system such as this:

    It draws 4.3 amps, 115v. If I had a separate cord running to the 20 amp service, it should work, shouldn't it? As for the plumbing, that wouldn't be too hard to set up. Any thoughts?

    I never used water in my PUP because I came up camping with water jugs. Now we have a TT and when I filled my tank on the first run, I totally forget the water heater filled up and I could have done dishes anyway. What I DID do, and did in the PUP, was use my coffee pot. 12 cups of hot water goes a long way!!

    Also, Coleman makes some nice table top units and they're MUCH cheaper than the unit you're looking at. Check it out...

    Happy camping!!

    We use a Coleman HWOD and love it. We use it for dishes, showers, inside the PUP and out. It does not need to be plugged or plumbed in because it runs on a rechargeable battery. We use it boondocking just the same as in a CG. We put it on charge each day while the sun is pounding on our solar panel and it is always ready to go. I bought mine used on CL, it was 3 years old then and I've had it for 3 years since; still running on the original battery. Can't beat it, IMO.

    I think the link took us to a more expensive unit. The one I was looking at is $125 @ Home Depot. The Coleman looks interesting. I'll have look at it more in depth. We just want the hot water for dishes, hot chocolate, things like that. DW is not a boon docker, so we will always be somewhere with showers, but portable hot water could come in handy.

    Can't beat the coleman hot water on demand...I have 2 of them, bought the second new one on sale for $149.00. Works very well.

    I used to have a portable on demand propane heater (Ecotemp L5) I used when I had our old pup. I had added a second water inlet port to the outside of the camper, so I had both a hot and cold feed. I also installed a residential faucet at the sink. It was inexpensive, and worked really well.

    We have these below in our construction trailers. Seem to work fine. I think they are Bosch units. May work well with pups

    We have something similar at home. It does not make enough hot water for us to do dishes using the 3 pot method. I have thought of put one in our HTT but am concerned about winterizing it. Not sure I want to have anti freeze in it for 4 or 5 months.

    That is a pretty neat setup. Where did you get the stand for the water heater?

    I made it. It's a piece of 1" perforated square steel that I welded a plate on the bottom of. Drilled a few holes to drive stakes into the ground. The heater has two keyhole slots on the back of it to hang it. I used two smaller carriage bolts on the stand that the heater hooks on to. That way I can easily remove the heater for storage.

    We just bought our first pup and were planning on adding an ecotemp inside. Our kids 7, 4, & 2 did not care for cold or luke warm campground showers. I was going to add a pump and larger tank to the pup. Then try to figure out how to construct a shower stall. Do you have any suggestions or warnings?

    We have the coleman too with all the accessories.

    We use it for hot water and shower duties along with the 2 room shower tent.

    I have the adapter that allows me to connect it directly to the water supply which is a big plus :)

    Ecotemp worked for me. You can use green bottles or #20 tanks. It will scald a dog. You do need a minimum of 40 LBS water pressure to make it work though.

    We have a Coleman HWOD unit. It's works great and I got a sprayer for it to do those large pots. But the one thing that I have noticed is when we use it on really cold trips it will run for a minute or so and then shut down. We are talking 25 degrees or lower. I don't think the battery likes those cold temps [?:~{]
