The absolute best ramp out there is the Scorpion Ramp.

It's nice and wide, so only 1 person to load, and folds into a compact size. It also can withstand twice as much as other folding ramps.

I didn't like my bike sitting so high, making my truck top heavy. I recently sold everything and got a drop tail trailer. No ramp needed as the back half drops hydraulically...

Your bike made your truck "top heavy"????????????? Come on!

 

you could always just back you truck into a ditch and load it from a yard. This solution wors for a once and while load not sure how often you'd need to do it

 

I use an 8' Black Widow. Works perfectly. I think they retail for $300, but I picked up mine on craigslist for $160.

 

The 10’ black widow provides ramp for every penny used. They have heavy duty aluminum leather. You can use them for your bike or for your garden tractors and other stuffs. They are a little bit handy and can be carried into back of your truck. They are used for beds of pick ups

I will second this as WTF?? Your truck is Top Heavy with a Bike in the back? Are you driving a Toyota???

 

A buddy had really nice (= expensive) aluminium ramps for his truck/bike, used them a couple of times, last time after he unloaded bike and went off riding, ramps were stolen. Found a raised berm in the median down the street, drove the bike into the truck bed on the horizontal, has used hills, ditches, loading docks at industrial buildings, loading ramp at the local HD dealer wherever he might be at the time, etc. ever since.The most it has cost him since losing the ramps is $20 as a tip for the warehouse guy at a company when he used their loading dock. At the rate he's going, it will be well over a century before he has spent what it would have cost to replace the stolen ramps.
