Hi everyone, Sorry I'm new to posting so please bear with me. We purchased the above motorhome last August privately. Unfortunately we discovered to our horror a couple of months down the road that the floor was rotten and had to be replaced. Unfortunately, the company we used to rectify the problem weren't all they were cracked up to be resulting in quite a bit of damage done to the vehicle including a broken rear window, electric step and new wall boards not refitted correctly. They also lost a small black box (it says water level sensor) which is in the wiring harness going to the large water tank. This part apparently is no longer available so I'm wondering if any of you out there may have a complete picture of this box or maybe able to advise on a solution. I've attached partial photos of its location
