I'm just restarting in the business and bought a used Blazer XL and want to mount it in my '96 Chevy G30. It came with everything except a fresh water tank. Jon-Don wants $1500 to mount. I figure I could mount it myself and have them tap the fuel line for $300 and save myself $1200. Am I being frugal or foolish wanting to do it myself? Is there any trick or secret to mounting a unit or is it as simple as placing the unit in the van, drilling the holes and attaching the bolts and mounting plates? Any help and advice is greatly appreciated!!!
