I have had the CH50-DH50 installed since winter of 2017 on my 2016 305RL, it useses about 20 amps per leg on 50 amp service and is comparable to 40,000 BTU gas. The really great thing about this unit is right now it is 20Degrees F. outside and 68 inside at 47% humidity in coach and basement is runs at 60 degrees where water pipes and holding tanks are.
I very seldom park where I only have 30 amp service, this is a great product for us.
