comments on 2003 allegro bus 40dp

You need to be aware that there is network dedicated to Tiffins at Tiffin RV Network that has a forum with many Tiffin owners that are extremely knowledgeable on Tiffin MHs. It is not ran by Tiffin but by a dedicated group of owners.

One common issue to check for (may or might not affect 03 Bus (Tiffin says 04 Bus and Phaetons)) but check for the 'wet bay problem'. If it has the problem, you'll notice the floor under the storage tanks is drooping down.

Hi Airplane Joe,
Is your Cummins turbo-ed? If so, it will handle the hills like a breeze. As to maintenance, I would make sure that all the fluids have been changed when necessary, as well as the fuel filters and dessicant filter for the air brakes, etc. I just recently purchased a low mileage 2005 Safari 40DP myself, and the fuel filters & desiccant filter looked original. I've found that when you buy a used rv, most of the time, unless you get good records on it, you should change out the fluids, including on the generator, to have a good starting point. I did all of this on my "new" one, and just came back from an uneventful 3,00 mile trip. The Tiffins are well built, top quality units, and should give many years of trouble-free service.
