Yep I like the idea of a a gas model, so im assuming this is an instantaneous and doesnt require a storage cylinder?Like CJ1177, I couldn't comment on DIY, but reckon fitting a gas/mains SUBURBAN would be a fairly straight forward job for one of the Jayco Service/Parts places.
I often free camp and nearly aways use mine on gas, so I would personally stay clear of straight 240v DOMETIC models unless you never (never intend to) free camp.
Ring one or two of the Jayco places for a quote (Prestige Geelong or Bendigo; Page Bros, Seaford; Jayco Bayswater, etc.) Have the discussion as to where it will fit best and where the SWITCH will be located.

Units are around the $800 retail, but I've also seen them on sale cheaper. Jayco would get them for quite a bit less I reckon and after market fitting/240 & 12v electrics/gas/plumbing is best left to qualified tradies.
Now (winter)would be a good time when they seen to be a bit quieter.
Really worth it for the sheer convenience of on demand hot water even when free camping. Add to your resale value of your Expanda, so it's a sound investment.
Is the install of the outside shower and plumbing fairly straight forward?Hi Sledge, I have the same van and have been thinking of doing the same thing. I have installed the outside shower and already done the hot and cold plumbing for it. The problem is the weight of the hws will add to the weight of the van. It depends where you are going to take your van. If you are just going to parks and you have 240V, Truma make an electric unit which would be really easy to put in. Suburban will be heavy, I have been thinking of the Girard instant gas unit recently approved for Australia.

As it does not store water it will be lighter, no anodes to worry about and will only heat water on demand. I would worry with an instant electric unit that I would take out the parks power supply.
Cost=Unit plus approvals in Australia. I am happy to wear the cost seeing it is approved for use in Australia. Regarding cost to run Brad, continuous flow units always use less gas than storage, but being continuous flow, people tend to use more hot water than they need because they can, therefore you can use more gas so you have to be sensible. The old saying when comparing storage to continuous, "would you boil the kettle all day for two cups of coffee!" Anyway, still have not decided what way to go.
No, it's a very efficient 22 litre insulated storage model with a porcelaine lined steel pressure tank made in USA. Thats the whole unit in the pic I posted. You don't need to leave it on all the time of course, that's why the switch location is important. I turn on when I get up, and off again after all the washes and dishes done. On again when starting dinner and off at bedtime. Haven't had an issue with it at all with auto ignition system. Heats in about 15 mins and maintains temp automatically.Yep I like the idea of a a gas model, so im assuming this is an instantaneous and doesnt require a storage cylinder?
