Hey Chris, I would highly recommend going with a Furrion tankless water heater like the part # FR98SR in place of your Suburban SW6DE. This is our best performing tankless unit that also will install relatively easy in place of what you have now as well. My parents had this in their last camper and really liked it over their tanked water heater they had previously you'll really like it too. Is the limited hot water with your current water heater frustrating?
