Hot Water Tank Replacement

I am considering replacing my 6 gallon hot water tank in my R-Pod 180 with a 10 gallon tank as I am tired of running out of water in the shower.  Has anyone done this type of replacement?  If so what tank brand did you install?

I just replaced our worn out 6 gal suburban with a duplicate.  It was a tight fit to get the new one in.  If you go to a bigger tank, be sure to check the dimensions and make sure it'll fit, both at the point where it is installed and passing it through the hole in the side of your trailer.  I took a look in Amazon at the hole dimensions needed to get a 10 gallon heater in and you're going to need about to add about 4" to the hole in the side of the trailer and a couple inches will be needed front to back.  Given the aluminum sidewall frame of the Pod, that may be a challenging mod.

I would first try the suggestions given here.  But after all that if you still want to replace your water heater,  a 10 gal will not fit.  I would go with the Truma AquaGo tankless water heater.  All the other tankless systems are junk compared to the Truma.  In fact, Lance puts them in their RV's.  One thing to note is that it is only efficient to use a tankless system if you are hooked up to water and sewer.  You will use more water which will quickly fill your waste tanks.  Boondocking and tankless water heat do not go hand in hand.  We were going to go tankless but after switching out the shower head and using both electric and propane to heat water at the same time we find that we never run out of hot water.  Amazing for a 6 gal tank especially since we run out at home with a 30 gal tank and had to go larger when the water heater needed replacing.

Truma also makes an interesting combo space and water heating system, much quieter than the jet turbine that comes with our trailers.  They make some good stuff, although I would hesitate to go so far as to call the Suburban unit "junk".  I suggested it because i expect it would be an easier DIY project than the Truma would be, being designed as a direct replacement for their 6  gallon ones.
