sealant for windows and sides of TT

I know this topic has been probably been brought up a million times, but what type of sealant should I be using on sides/window/various seams on SIDES of travel trailer. My owners manual actually says use silicone, but I know silicone wont last in the sun/weather.
Do I have to match the existing sealant that is on there now or will other brands bond to what I have?
I think I have heard some people talk about using Pro Flex...
I want a product that will hold up well.
Thanks

    Do I assume correctly that you pull off the painters tape while the caulk is still wet?

    You can also use Proflex RV or Tremco Proglaze. The latter is less messy to work with. Both are used by RV manufacturers.

    Yes pull the tape off while its still wet.

    Our local RV dealer/supplier, who has been in business for decades, uses and recommends "Nuflex 313 glass and vinyl fast set silicone" for windows. I had a gusher coming in one of my windows, so I removed the window, cleaned everything thoroughly and then placed putty tape under the window flange, when I reinstalled it. I followed that with the Nuflex and got a great, professional looking result. I removed the bead around all the other windows in the camper and put a bead of the Nuflex on all of them. I am very happy with the result.

    The dealer recommended this stuff for SIDES of RVs. FWIW, my camper has aluminum siding.

    P.S. I agree with TrevorL about using painter's tape to get a nice sharp edge on your caulking.
