My Dicor feels like the Pillsbury Dough Boy

Maybe on a few units the décor was to hot coming out of the nozzle and it caused the air pockets.

New or used tc ? If used, someone might have not prepped the area correctly being Dicored. Actually that could happen to a new unit as well....unfortunately .
also, dicor has a shelf life, it might have been old stuff and just lifted in certain spots .
Clean it up and redo it . No leaking , you'll be fine .

2013, would this still be under warranty? (If sealant covered)

So does mine. How is the sealant that overlaps the cap to the roof? I'm having issues with mine and looks like I'll be replacing the roof very soon because of it. I found out that back in 2011, RV manufacturers started using new formulations of roofing material that had come into the RV marketplace. It seems that some roofing membranes are not chemically compatible with current lap sealants. When these sealants are used on some new membranes, bloating and disfiguration of the membranes results. If you have purchased a 2011, 2012 or later RV model you might want to be aware of this when doing significant repair work that involves resealing the roof membrane. I'm not looking forward to having this done as this is going to cost me an arm and a leg but it has to be done since I have experienced water intrusion.

I read what you are talking about on the Dicor website. In fact I posted that info just the other day. Dicor states that it only pertains to TPO roofs and that the bubbling is only cosmetic and does not ruin the integrity of the TPO roof.

They do make another product, called Ultra Sealant for the newer TPO roofing material.

If your TPO roofing material has a fuzzy felt like underside then you have the older TPO roof and the regular Dicor will work just fine.

The thought has certainly crossed my mind....

You are correct in assuming that the Dicor should be fairly solid to the touch and not puffy. Sorry I have no suggestions why there would be those puffy areas.
