Question about Water Heater for food truck/trailer

Hi all,
 
So, the health department here tells me that I need a water heater that's big enough and powerful enough to provide hot water for my 3-compartment sink, prep sink and hand washing sink. Problem is, I don't have a ton of space for a real big one and I'd like to keep the costs down if possible. I'm looking for something in the 10-12 gallon range, electric, that can put out a min of 2kw power. My trailer is wired for 120volts and I've got 20amp circuit breakers. Maybe I'm going down the wrong road looking for an electric one, and should look into gas? I've looked at tankless, but there's nothing that would have a flow rate sufficient for filling up a sink and is compatible with 120volts. Any ideas? The HD is being pretty particular.
 
Thanks!

    Go with either a tankless or a 10 gallon RV  water heater (I'm partial to the Atwood brand but that's what's in the Class C and we showered with a 6 gallon unit). Either way, you are looking at LP units. We like the tankless Eccotemp L5 we have. Downside is that with below freezing night temps here n NM, the tankless heaters will only raise the water temp a certain amount. David has had to heat the water on the burner a few times to get it hot enough to wash dishes. Ours is not vented outside (cart leaks like a sieve in the wind) but with a little fiddling, we can mount an exhaust on it. Right now, it's helping to keep David warm!

    I will also say the L5, Mine has been running great.I have quick dissconects on mine because I can not leave it in there overnight. Going to try to incororate a block heater in my water tank this summer to try to keep the water warm before going thru the L5

    Thanks, all, for the advice. Unfortunately, the HD won't let me use the L5-- not enough power for them. That's really my issue-- finding something with enough power that's still small enough to fit and won't blow my 20 amp breakers. The 10-gallon RV style heater may be the only solution, but it's still quite bulky. Frustrating stuff.
    I'm curious-- if you detach the L5 every night, how do you warm everything back up the next morning so as not to blow it out when you restart it?

    If not the L5 how about the L10 ? I have to take mine out as the below zero weather cracked the last one. Simple when we are done for the night I pull it out sit it in the warm truck then carry it in the house. As far as warming up the trailer I have all my furnace hoses and ducts aimed at the water tanks Potable and non potable I crank up the furnace first thing ,Then light the griddle at -20 takes 10 min to heat the trailer up by the time I get everything out of the truck that needs to go back in the trailer it's warm. On another note after I take the heater out I have quick disconnect for both the LP and water line on the heater I just turn on all the sinks and blow out the lines

    We leave our L5 in the cart. We stick a 60Watt incandescent bulb under the sink and prop a couple sheets of Reflectix over the open front of the sink area (all our plumbing & the battery). the floor and back & sides under the sink have been lined with Reflectix as well.

    Are you still looking for a small water heater?  I have a brand new still in box 6 gallon Rheem that I didn't use in my truck build we ended up using a 6 gallon Eemax.  If you interested, please message me.
