Newell uses the most pneumatic systems of any coach out there. The systems develop leaks, usually at the push on fittings. Rarely does a line need to be replaced. Any newell owner should develop the skills to find and repair air leaks. If you pay someone else to do it, you will go back broke and be be very unhappy with the results. The slide system and door problems are very likely caused by air system issues. The work is not hard but it does take time, and time at 150 an hour adds up quickly.

Take some time to read the section on Things to Consider when Buying a Used Newell, and many of your questions will have detailed answers.
