Default Caulk for showerpan

I recaulked the shower pan with ProFlexRV caulk. https://www.amazon.com/Geocel-28101V.../dp/B004RCP49O

I fully removed the old caulk and cleaned with mineral spirits before applying new caulk.

About 1 year has gone by since I did this.

It does not seem to adhere well to the fiberglass walls however as it has developed several cracks along the caulk and the wall. I suspect there is a lot of flex when driving, causing the caulk to release in places along the wall leaving a visible "gap".

What type of caulk have others used here? Just basic bath/shower silicone type caulk, or something that is more specific to RV use, and in turn the flex that will occur.

Thanks for suggestions.
