Took my motorhome to Watling Engineers today to have a tow bar fitted. By the way it is a work of art, but that is not why I am posting. Speaking to the engineer before fitting I mentioned that I was having rear air assist fitted next week by Glide Rite and would that make a difference to his work. He advised that, due to air assist raising the vehicle slightly, it would have been better for that to have been done first so that he could make sure the vehicle level was correct after the work. He did say that it would not be a problem. Has anyone had a problem with levels after air assist has been fitted?
