I was surprised that my local RV dealer had competitive prices on many repair supplies... and outrageous prices on others. Butyl tape is one of the items that was priced the same as Amazon and the rest of the web.
The local RV dealer also told me to just use silicone which is what their repair department doess even though they had the special RV caulk (Proflex) and everyone else in the world says to use RV caulk... I bought the RV caulk.
Everything else I buy off of Amazon. It seems like everything over $25 is marked up 100% at the RV dealer. I guess even though I get free shipping through Amazon prime shipping is built into the Amazon prime price making the local RV dealer competitive.
