So I've done some exploration... I'm fairly certain the vents are damaged beyond where I can see. I've cleaned a ton of nest material out of the middle vent. Crazy story regarding that later. I've got two of the vents operational, but the one in the front is going to be an operation.
Almot, Bikendan, I have used my camper in all kinds of weather. You're right, 3 seasons in the south. :D I thought about just removing the heater, but with a youngin and space at a premium, I'm thinking to keep it.
If I have to remove the bottom to redo the front, I will be doing a full replace with hard piping.
Doug, I figured the ducting would be different, but I try to go with the simplest explanation. So it is "basically" the same, just more upgraded. :D
I'm still debating on how I want to proceed. It looks like the bottom isn't too involved to drop. How hard is it to do that?
