My '97 5er has had nothing but a bit of Dicor added to a few spots where the mfg sealant had small hairline cracks. The unit has never leaked as I do a twice a year roof inspection.
Eternabond is great stuff but is not a product you install and forget roof inspection.
Better ask your new trailer mfg and dealer about warranty issues before installing Eternabond up there...it can void the roof warranty as one RV.net member found out.

A while back, I opened a thread asking whether eterna-bonding the roof seams on an almost-new TT as a preventative measure was a good idea ...the virtually unanimous opinion was 'yes'....
Well, took the TT to the selling dealer today for some minor work...rep. sees the tape job, asks 'why on earth did you DO that'?, and tells me that: a.) it's not necessary b.) it'll trap water if any water ever gets beneath the tape, and c.) any claim under the roof warranty may get kicked on grounds that the roof has been 'modified'....
thought i did the right thing by sealing the seams, but now not so sure....
