How do I get at the suburban water heater control board?

[Elconrado]

I need to replace the control board for my Suburban SW6D water heater. I have a 2017 Wildwood T190RBXL. I'll get a Dinosaur UIB-S board.
The problem is I cannot get at it to replace it. I've taken off the access point in the bathroom but the board is on the other side of the water tank and there is no room to get to it. I've looked at the access panel at the back of the trailer but there does not appear to be any way to access the control board without basically removing everything to do with the heater. Anyone got any advice as to how to do this? I've read many posts about replacing this control board and I've seen video of people accessing it. However I cannot see how to get to my one?
