Hi, the roof top air conditioner drain keeps dripping on the door of the camper. is there any way we can adjust a hose or something to redirect the drainage? the camper is Coleman Pop up and the air conditioner is a 7300 series.

Re: re-directing the water dripping over door ! Stop at RV parts store and get yourself a tube of "Dicor" self leveling sealant. It's recommended for rubber roofs, but works well on most roof surfaces.
Then I simply run a 3/8" bead of "Dicor" across wherever the run-off from AC is coming down, and re-direct it so the run-off comes off roof elsewhere. Don't try to smooth it out or anything, as I said, it is self leveling, just use a caulking gun, lay a bead about 3/8" and allow it to set for a few hours if you can. Make sure you pick a time where AC is off for a couple hours so (run-off) water isn't present. You"ll see the path (stain) on roof where it travels to guide you for redirecting. It's a simple fix, and no screws or nails required. Use the rest of the Dicor to fill in any gaps, cracks etc you see on sealant on the roof while your up there, but clean those before applying. If you can wipe your intended path down with some mild cleaner prior to applying bead, it will help it stick better as well. Even a little dish soap in water will do, just be careful, it gets pretty slippery when soap on there. Quick rinse with water then dry with rag, or let the sun dry it. Actually on a rubber roof, It should be scrubbed with mild detergent at least once a season anyway.
