We inherited a pair of yellow Fiamma ramps with a caravan we bought in 2001 and and also used them with that caravan's replacement (1300 kg MTLM) until we sold it and bought the MH this year. However, the MH handbrake has some backlash so the wheels just roll back down the ramp unless used with chocks. IMO having someone wedge a chock under the wheel while the MH is held on the clutch is potentially dangerous and having to release the chock makes getting off the ramps 'interesting'. So we've bought a pair of Milenco Tridents -- the steps should get around the tendency for the wheels to roll back down the ramp. That said, they're still pristine and unused as everywhere we've pitched since getting the Tridents hasn't needed ramps!
