Increase the LP mounting frame base by 2.5"
Iím planning something similar. I need about a 1Ē lift for the tanks. Iíd just make darn sure the tray is either bolted on well, or properly welded in place for safe retention of the tanks.
Realize that Airstream only used four 3/16Ē diameter self-tapping screws to sort of hold the tank platform on my 2007 International CCD. Doesnít make me really comfortable.
