Camper Insulation? Air Conditioner Insulation?

I recently purchased a 1984 Resort(Fleetwood) and I had to redo the back end of the camper, I removed regular fiberglass insulation from it, and I need to know what type of insulation I should use? I was told to use R11 which is over 3 inches thick by a hardware store. Is this a good choice or do you have any suggestions?

Also the camper has a Coleman TSR Air Conditioner but that is all I know, but there is exposed insulation right by the vents were the air blows. I am not sure if this is supposed to be there are not. And I don't know if the insulation is orginal or not. Any suggestions?

Attached are pictures so you can get a better view to help answer my questions.

Thanks.

I'd use the foam board, as thick as will fit. Might be more expensive than fiberglass but it won't absorb water if it leaks again.

Not to mention it will insulate better.

Mashing fiberglass insulation to a lesser thickness will actually decrease the R value.

Rigid board is a better insulator than batts, but you may have gaps with all that cutting. I'd try an expanding foam spray to fill them. If you're not familiar with it, it comes in minimal expanding form, which might not get away from you.

Thanks for all your suggestions! I think I'm going to try foam board. Any suggestions on the air conditioner?

Agree with using the foamboard. When you go to get the canned foam ask for "NON-EXPANDING FOAM" You can use that to tack your insulation in and to fill in the gaps. Should make the trailer nice and snug. It may take several cans.

Sorry, I can't help with the AC. Out of my pay grade.

I used foam board to re-insulate our 85 Wilderness after repairing water damage, stuffed fibreglass insulation in the small gaps in the foamboard.

Because of the constant movement, this is a great idea. Foam, sprayed in gaps, will separate and create gaps.

I wouldn't want exposed fiberglass insulation at/near the air conditioner. Is there a way to use aluminum tape to seal the exposed areas? Aluminum tape is sold at virtually all home supply/hardware stores for sealing cracks, seams, and holes. The cold-air plenum should be sealed to prevent losing cold air into the ceiling, and to prevent cold air from blowing into the return air plenum; ie: you don't want cross-contamination of cold air and return air.

For the rear wall area, consider 2" thick insulation, the 3" would have to be compressed like Ken said.

We do insulation on commercial bld. On the raw Fiberglas. You will need to buy a spray can of adhesive. To spray on the yellow f/g then use the tape .
The foam board will be very good for the back .
You can get that at lowes or h- d in pink or blue

If you irregular. Shapes then the foam can will do a good job on a filler , if not stuff with f/g then alium tape
