Air Conditioner drain

It's normal especially on an entry level coach. The water will go whatever direction gravity takes it. It's really not an issue.

Is it possible to run a drain hose into one of the vent pipes, this way it would drain into one of your tanks

Our motorhome has hoses on both units and the water drains out underneath the front and the back of the coach. If yours has that, maybe the hose is plugged or kinked.

Yes, buy a rig where they ran a $10 drain line from the AC's pan to the ground internally. Above my windshield there is a rubber channel that keeps runoff off of the windshield... guess you could add something like that along your sides to channel the water to one spot where you could add the little spouts like on your 5er.

It's pretty much going to drain in the direction the coach is leaning.

Are there no gutters on it? They might be clogged.
