Here is the info from thier web site
• Adjustable ramp width for wide or narrow track vehicles
• Accommodates up to 122" wheel base vehicles with a gross weight of 7000 lbs. including Tahoes, Durangos, and pick-ups
• Ramps are 18" wide and 17' long
• Adjustable Ramp Height - 16-18-20-22"
• Removable Approach Ramps - ramps reduce overall length by 24" from 17' to 15'

Probably more than I need for anSPF but hey maybe the G500 will look good up there
