One of the neat things about a forum group is that there are tons of different folks, each having their own set of knowledge on RV. There are the mechanical folks who have had hands on, the theory folks who have been to school, etc. and then there are others who have sources to info like pictures or written info.
If we can accept that all that info can have great value, depending on the situation, it really helps solve the problems that we all may find!
And one of the big things I have learned about RV is how many small points are actually different at different times. We can have "exactly" the same RV but they can be different when we look closer! Exactly the same is not always the same!
Your water heater may be one of those as I noticed what shows in the pictures was not the same as what I had found in the drawings. First thought was that I might have gotten on the wrong RV along the path to the drawings, so I went back to do a second look! Expect to be right but also assume I might make mistakes?
So when I took a second look, I found the disconnect in the two sources of info as there are two different water heaters used on your year, make, model floorplan for your RV!
The difference may be a brand change or possibly the water heater builders did a change but the motoraid connections show up as different!
Sometimes we can go with info we find but other times it also pays to go into the job with an open mind and figure it out as we go because we may be missing some tiny point like when the RV was built!
I'm betting 90% of us can't say if our RV was built before October 20 or after, without going to yet more info to check!
That's where we may need to be aware of the label Winn puts on the RV with that build date! Driver's left side is a common place to find lots of the critical info we need when we want parts info. Especially important to know when we want to order chassis parts like brakes!
It's like a big Easter egg hunt?
We have to look under ALL the bushes to get the best result!
