We have a Bailey Pegasus Messina van. Wanted to mount TV bracket to side wall of fridge so I spoke to Bailey about this. They said the wall was not suitable to mount a bracket on. This dealer clearly did not speak to them before they carried out the work nor did they read the instructions. I would speak to Bailey direct to confirm if the wall can be used to mount a bracket on. If they say it is not suitable reject the van and go to another dealer to buy a new one because if they think that is the correct way to mount the bracket I would not trust them again.
