Hi Trevor and Tracy.
Here are some thoughts after three years of owning an Oxygen. If I think of more I will add to this post:
1) We love this Rig!
2) It pulls easy. We get about 20 miles per imperial gallon when pulling with our 4 liter 1999 Explorer.
3) The bed is difficult to make, being surrounded by walls on 3.5 sides. Also getting in and out is a trick. It was always a debate with us which end to rest our heads. Try all positions 'till you find one you like.
4) We made a new hinged base for the bed out of 3/8 plywood and threw away the pieces of plywood that covered the openings. MUCH easier to access the storage.
5) You have already experienced the falling kitchen window. Beware, others may follow if you don't wire or glue the latches. At the very least, check all latches before travelling each day.
6) The refigerator control only controls actual temperature on 110 volts. I don't think this is unique to this trailer. 12 volts will surely freeze all. We used propane
while travelling. Just remember to shut off BEFORE you pull into a gas station.
7) We installed a shower in ours and found it one of the most used add-ons. I posted the instructions a long time ago, but they have been wiped out. If you are interested I will post again.
8) Only one instance of problems pulling. We almost flipped it coming through Montana. Side winds were gusting to 70 mph. We were nuts to be there.
9) Lock both locks on the door. If you don't, the door may fly open while you are travelling.
10) When you have filled the water tank, turn on the pump and turn on the hot water tap. This will fill the hot water tank also, and you can put 10 more gallons in the tank.
11) Leave the black water drain closed and put a drain hose on the sewer cap and run grey water into a 10 gallon jug. This will give you much needed space in your black water tank. (when you're not connected to sewer)
12) You will have to put up with LOTS of looky-loos. Be nice, after all, you are the one with the weird looking RV. I thought of charging for tours. Could have made a LOT of cash, but we met lots of nice folks instead.
13) We love this rig!
Again, Have fun. This rig is incredibly strong. I don't think you could break it unless you rolled it. Even then, I suspect it would be salvageable.
