Steve, if you want a reliable mover then definately DO NOT get the reich,i had powerwheel movers fitted to my previous coachman pastiche 520 and my coachman laser 520 i allso had one fitted to the ace twin axle i had for a short while, when i bought my coachman vip530 the dealer asked me to leave the powerwheel on the ace and he would fit me a new one to the coachman. he fitted a reich mover and its the absolutely rubbish.
the coachman 530/4 is a very similar weight to my old pastiche and the powerwheel had no problems getting the van up my drive (any of the vans) but the reich is appaling, it just gives up and trips out, i have to have my wife and my daughter pushing the van along with the mover to get the van up a simple dropped kirb on to my drive which allthough slopping is not too steep. its been back twice and both times reich's engineer has said the mover is working as it should, i guess its designed not to work then !.
another big problem with the reich is the mover is very low to the ground and the plastic covers are very brittle and break easily on even the lowest of speed bumps.
your friend wont be a friend for long if you have one of these awfull movers fitted. have a look round site and you will see the vast majority of movers are powerwheel that should be testiment in its self.
