In an effort to keep this simple:
I'm not trying to sell to the masses, or even to anyone on this forum. I'm certainly not inventing a robot that will do your dishes or clean your windows.
Let's say, if you're lucky enough to pull into a park and someone was there who offered this service and had the time, would you like to never worry about your tanks again. I think people that RV grow used to certain tasks that go with the lifestyle, but we don't have to. Pulling a lever is easy, sure. But when a grey or galley tank fills up at the wrong time, or a black tank burps odor, I would have to put on shoes, walk out in the heat, rain, ice, or dark, to dump, go back a little later to close it. It was an annoyance. Now, I don't ever have to think of it, and I LOVE it. It does work VERY well. Maybe new RVers would like it because they haven't grown accustomed to the ever present duty of managing their doody. I forgot to mention, I also haven't needed any tank chemicals since March, not a hint of odor or build up.
darsben-I've owned several businesses, so you're not thinking of anything revolutionary. I have a job, so this would not be full time or to make a living. What do we get when we assume?
dahkota-The bulk of the unit is another water hose, and it adds less than 5min to setup after your first time.
I've only shown it to a few people, and they're blown away at how convenient it is. $200 is just a range to give an idea so we know we aren't talking about a $20 or $2000 fix. Custom fits would obviously have to be taken into consideration. I also custom fit my other hoses, so my entire system very tidy. Extension hoses are stowed away if needed, but the common use hoses are only as long as they need to be.
Thanks to those with open minded input.
