6ft ramp sounds a little short. But, I'm used to my 4x4 Ram.
Rent a trailer with the truck. I hook up my trailer, then put my ramp from the trailer to the bed of the truck. Makes loading/unloading easy. Plus, bikes that go to the gap don't always come back undamaged... Much easier to carry a bike on to a trailer than lift one into the back of a truck
If times permits, I'll definitely give this some thought.
I put 2 sport bikes in the back of an Avalanche before. 1 in front wheel forward, the other backed in. Tied them both up independently. 1 strap around the triple/steering stem and 1 to each of the pass. peg area of the frame. 6 straps in total.
1 forward/1 backward for lack of bed width? Its nice to know others have done this. I'm thinking roughly the same idea, except with the inside tiedowns passing through the other bikes spokes to the tiedown points on the opposite side of the bed. I'll be using 12 tiedowns, 8 softstraps, and 2 canyon dancers. I'm imagining- 1st bike in, sidestand down, 2nd bike in. Mount canyon dancer to 2nd bike, running the inside tiedown through the 1st bikes spokes. Sidestand up on 1st bike, mount canyon dancer and route inside tiedown same as 2nd bike. Bikes are secured, mount all additional tiedowns/softstraps at my leisure.
6ft ramp sounds a little short.
From the ground to the bed, wayy too short. I'll be loading the bikes on the top level of a 4ft walkway dividing adjacent parking lots . Backing the truck up to the bottom stair, I figure the tailgate will on be maybe 4ft away(if that) from the loading point. The ramp will be pretty damn level, maybe even have a slight downward slope.
BTW its CHOCK, not chalk. Chalk is for writing on pavement or slate boards.
LOL, you know, I actually thought it the right way, but subconsciously spelled it wrong. Kinda like brake and break, I guess.
