If properly done, the new seal is likely the best improvement Scamp
has made in decades.
I have worked with several different seals over the years and find this new one to be the best by far.
The only problem is that it is more substantial than the open cell original gasket and may require a little time for break-in, or in some cases a shim on the latch or hinges.
Of the several which I have installed or helped install, a couple have been a little difficult to compress on the hinge side which could mean more effort to close and latch during break-in.
I had such a low opinion of the original gasket(2004)that I immediately replaced it with an "Omega" shaped seal which worked well, we then switched to a "D" shape which was more aesthetically appealing. This gasket was later offered aftermarket by Scamp
for a few years and then they had the new gasket made and began installing it as OEM last year.
The fit of the door will affect the initial seal, but the new seal has a wing which flexes to close small gaps.
As a caveat, I must say that I replaced my latch at the same time as I replaced my first gasket with a much improved RV latch.
Of course...to paraphrase a very famous lie ,
"If you like your seal you can keep your seal"
