roof type

[Kzneft]

If you log into the Keystone factory you can download the user manual for your particular year of RV and it will tell you what type of roof you have. Mine is a 2018 Keystone Carbon, and my manual says Rubber TPO roof.

I have contacted Dicor through the webform....now about 3 weeks ago, but unfortunately they don't answer me... perhaps if someone here on the forum could post me a pic of the label on the dicor product, that could be very helpful to me... so I know what to look for here, and what I should be careful with... I suppose not all products are to be used for a TPO roof...
And what product I could use for caulking things like hinges (storage doors, windows..) since I see they are not sealed off...

For hinges you can use clear silicone. For the roof its Dicor 501. For vertical seams OSI quad or Dicor 551 should work.

Dicor also has a 351product... what difference is there with the 551 product?

I don't really know... 351 is listed as cap sealant for front cap, rear cap, windows etc. 551 is roof non-leveling lap sealant. 351 may not be safe for roofs but 551 is. 551 likely works fine in the other areas... but I'll let someone with more experience with both confirm that
