My wet bath 1975 Glenbrook has a leaky water heater. It's the 6 gal Attwood rectangular, electric and coolant heat exchanger type. I have a replacement unit and the original unit completely disconnected and everything cleared from under the bathroom sink, but there doesn't seem to be enough space under there to get it out. What am I missing? I thought that the heater would tip up, then down and out, but I can't figure it out. I need some pointers or direction as to what needs to be done. Thanks in advance

If this is an old Atwood rectangular unit you might find some help at
GMCMI.COM
Click on The GMC Motorhome and then on the drop down menu Technical Seminar Handouts, then click on Bathrooms.
There is a very old article on the removal.

I have a 75 Glenbrook, and just changed mine out two months ago. There were two heavy metal straps over the heater that hooked on the exterior side of the platform the heater sat on, and had eyebolts on the interior side - got both of those off? I pulled my whole bath rear wall (removed rear cabinet, fold down seats, etc.) off and went that route. My new water heater had different mounts on the ends, and was just a little too wide to reuse the over straps, so having the back wall off made securing it possible. My biggest problem was finding connectors for all the wacky sizes of heater and old plumbing. My next biggest problem was getting the air out of the engine coolant lines once it was all back together. If you don't have a filler built into the cab heater line (up high in front of radiator), I would suggest unhooking the rear engine to bath supply line and beginning your coolant refill from there (fill towards the bath). Put the rear line back on the engine when full, then fill at radiator. Then run engine just long enough to get the thermostat open for a minute or two, then let it sit with a full overflow reservoir. Repeat the engine run cool off cycle again the next day and refill reservoir. JWIWD

Pull the frame that houses the sliding doors. I believe they are held on
with several screws around the frame.
