Seen it before but funny 
You may think thats funny but it aint■■? 
I once put a bedford CF on a small trailer hooked up to a ■■■■■■ Van and took off down the road then when I had to hit the brakes and it lifted the back of the van up in the air and I was looking at Tarmac 
Bully
During the sugar beet season when I was a kid we use to wheelie the tractors.
If you get a good load on the trailer & then snap the clutch the front wheels go up nicely if you are on a muddy field.
Also use to do a similar trick with dump trucks.
If you drop the bucket down on the small older dump trucks you can restrict the tip by use of a chain. If you use the chain to hold the front of the bucket horizontal & then load the bucket with concrete blocks all the weight is in front of the front wheels. This added to the fact that dump trucks are rear wheel steer allows you to spin the truck on it’s front wheels. We use to use this to stop anyone nicking the dump truck, we would put the truck in an impossible position, unload the blocks & then go home.
