Thank you everyone for your responses; its’ good to hear the pro and con experiences.
Some of the con issues I have is that my warranty will not cover electric valves as they are not original equipment and they are more expensive than the manual valves. Some of the pro issues are that, as SuperDutyFiver stated, I will have a control panel inside my 5’er and do not have to go outside to dump my tanks, and Camping World, whom I’ve made an appointment with to install 3-electric valves and the panels, offers a 4-year extended warranty on parts and labor at $20/valve. They are also right now offering a $29 installment special.
I have a 2012 Heartland Prowler 5th Wheel and if it was much older I probably would not upgrade the valves; not wanting to spend the money, etc., but all 3 of my manual pull cable type valves, 1-black & 2-gray, went out only after having this brand new 5’er for about 15-months. My warranty will cover replacement of the pull-type cable valves but this is the first RV I’ve had with pull-type cable valves and I have very quickly grown to not like them.
