Also check out Sikaflex 252. Source: austinhardware.com just type 252 in the search box. This product is used in the manufacture of commercial truck & trailer bodies.
I set up a scrap piece of steel sq tubing & bonded another scrap of .050 aluminum to it aprox a foot long. After it cured, I couldn't separate the them (even with Visegrips) without destroying the aluminum.
If I build another motorhome shell, I would use the Sikaflex over 3M VHB without any hesitation.
