For the DIYers. Be careful choosing roof sealants
I believe most of Grand Design units these days have an Alpha Systems Superflex TPO roof membrane. Alpha has a warranty that extends for 12 plus years. You should read the warranty found at AlphaSystemsLLC.com You will find that you could void your warranty or be denied a claim if you use other than an a Alpha product as a component this includes sealants. On their informational sites they say in bold text “ONLY ALPHA BRAND SEALANT CAN COME IN CONTACT WITH ALPHA ROOF MEMBRANE”. The other item to make note of is that the roof must be inspected at least every quarter and the inspection must be documented.

Alpha needs to make their product more widely available and at a comparable cost to Dicor
3 times the cost over Dicor. No excuse for that
Companies need to step up
But on my last trailer Jayco ,Jayco said to use Dicor. They informed me that the roofing would bubble which it did but settle in time. Which it did

Unfortunately claims personnel are heartless. I speak from much experience. I’m thinking of writing a book titled: Know what your getting into before you purchase an RV.

The following link is from the Alpha systems home page. I recommend everyone read the Alpha warranty information. It is an interesting read.

It looks like Lippert is carrying official Alpha System products now.

Also FYI - there apparently is (or at least was) a lot of Alpha sealant sold on Amazon that Alpha says was counterfeit. Unclear exactly how, but there were examples of almost-but-not-quite labels, etc. Apparently real Alpha sealants have an expiration date. Maybe the Amazon stock was expired, and re-labeled?
Between throwing away what apparently were counterfeits, and the expired tubes from my stock, and the hard-to-get nature, I've kind of given up.
My dealer, that generally is excellent, was unaware of the warning not to use other brands, and noted that since they started as one of the first GD dealers in the country they have only used Dicor. I did too on a few small areas, and haven't noticed any issues there or where the dealer did same when they added on vent fans before we bought it. So no warranty claim for me, but at least my roof stays sealed.2017 Imagine 2670MK

I have used both. The dicor looks, flows, smells, and sets up the same as the Alpha. I think it is the same stuff. I seriously doubt anyone could point to the dicor on my roof out of the alpha.
BTW, I got a blank stare at the dealer when I tried to buy some Alpha from them. They only use and sell Dicor.2021 398M Full Body Paint 8k axles. LRH tires. Disc brakes.
