A bare tub is like 500 lbs. How big are your 4 guy's?
A tub is 500 but add in doors, hoods, etc and it adds up. Especially if glass is on the car.
A simple cart on wheels will make it a lot easier. Can you rent some kind of cart.
If I was doing it myself, I would put a hitch on the trailer (harbor freight sells one for $25 with a nylon strap that is made for this) and then use motorcycle ramps to pull it onto the trailer. Lay a bunch of cardboard on the ramps to reduce friction or get two furniture dollies under the car with wide ramps.
Or get the car high enough to just slide onto the trailer by hand.
