I have used a tilt deck trailer and did not like it for me. When I had mud or wet tires it felt very unsafe. I also like loading other implements on the trailer first with the loader then put the tractor on. Very tough with a tilt deck.
To me a tilt deck is for a guy with a classic car who only takes it out in good weather. Ramps are fool proof, not as much trouble as many think they are, and always work. They are also much lighter. A 18' tilt deck trailer can be as much as 500# heavier.
Get a low boy trailer like mine with no dove tail and rear slide in ramps. My trailer is 18' long and only 14" deck height. With 5' ramps my angle is very low. I have no issue loading Corvettes if that gives you a idea. I can pull the pins and have the ramps in place in about 20 seconds each if I take my time and store the pins. Usually 30 seconds total for the ramps to come out or back in.
Wood deck is also the only way to go for slippery situations. Never seen a tilt with a wood deck, only steel.
