I purchased my 8.1 2002 Chevy 3500 155" WB Express Van ten years ago this week from Huffines Chevrolet in Lewisville Texas.Before that we had two PSD Excursions (7.3 & 6.0) and I prefer the 8.1 van because we only use it a few times a year and it has much higher payload capacity with much more storage behind the last bench seat since it is the 12 passenger version on the 15 passenger 155" WB chassis. It feels just like the 2003 6.0 PSD Excursion in power when fully loaded (not towing) with 11-12 people & luggage on Summer trips to Florida with AC on. It could sit for a month in the driveway without using it and it starts up like it was just run. It has every option available with 3.73 posi and LT265/75R16E 31.7" tires. The 16x8" alloy wheels would work with LT285/75R16E tires but I will stick with the 265s.
