my star trek ramps are breaking! worst one is left side which has a large crack under the metal protector and the other to ramps have fractures.i can buy the 3 ramps new here in Australia for around $600 aud,however im worried it will only happen again with another 13 months use!. am I the only one this is happening to? is there any extra protection available? I recently sold a 2 owner star trek 25th anniversary,i know the first owner,the ramps were perfect,never replaced from new,lasted 25 odd years,6 years commercially operated.surely a stern ramp should last longer ? thanks!
