Its not just rv folks that found out by actual experience pure silicone didn't bond well when used as a sealant. That depends on the class silicone used.
GE has three different class of silicone sealants for exterior use.(doors and windows)
a all purpose class 25...
a advanced all purpose class 35 with 5X stronger adhesion...
a supreme silicone class 50 with 7X stronger adhesion...
Probably why some silicone users had no adhesion issues and others did. I'm sure other silicone brands are about the same as GE.
Lots of info on the net from rv forums/boating repair shops/construction trades/etc about wrong class of silicone lack of adhesion issues.

I'm not sure this is the best stuff, but it's what ORV uses. It has a "a bit of self leveling" attribute to it, but not in a runny way. So when you apply it to clearnace lights or hatches it will just lay down a little to make a smooth application. When you need to remove it, it comes up nicely with a heat gun and a putty knife with rounded edges. Geocel 2300 Clear Tripolymer Construction & Pro Roofing

I SECOND this !
IMHO, there is NO PERFECT SEALANT/CAULK ! They all will eventually leak, some sooner than others. Add in the fact that on any RV the "joint" is going to move.
Butyl tape is perfect for a joint that can be disassembled. It is easy to remove and leaves little or no residue.
