Allegro Bus 2010-2015 Changes

Hi All, we are currently looking to purchase an Allegro Bus, considering years 2010-2015. Wondering if there were any significant changes during those years that we should be aware of? If there is something significant that would have us choose at one year over another(other than price)?

Allegro Bus 2010-2015 Changes

Well, for starters, late 2012 to 2015 avoids the Big 3 issues so I would personally limit my search to 2013 and newer unless you want to verify each issue has been previously corrected for the earlier years.

Nothing wrong with the earlier years, you just need to be diligent with the Big 3 fixes. Tiffin did many of them, so if you find a coach that you really like you can call them with the VIN and they can look it up.

Also, make sure you check maintenance records, especially the coolant. If the Freightliner coolant isn’t correctly maintained it can result in costly repairs later due to liner pitting. I would also get an inspection and fluid analysis on any Coach you are considering buying.

There were some major changes between the 2010 and 2015 tag axle models. 2013 was the last year of the 43' model. 2014 and later were 45' with a shorter dash and longer living room. I think the front axle rating was increased to 15,660# from 14,600# in 2012. Many with the lighter axle 43' models were overloaded on the steer axle in part due to the 60/40 proportioning valve used on the Powerglide chassis. But,,, if you are looking at the 40' or shorter, the only thing I would wonder is how is the front axle loaded? If considering a tag axle, the aforementioned issues need to be addressed.

I believe at some point the engines switched to requiring DEF; I could be mistaken.

Our 2014 40SP had what I believe may have been the first year for Spyder control of lights instead of a bunch of switches. Really like that Bus. Also remote control of shades. Also it was all electric with heated floors. Very nice. Older coaches will have service issues with the aquahot since it will be several years old and need attention at times. Jk

Don’t know about the other years and models but we had a 2014 LP 45 foot and absolutely loved it. Had to downsize for a variety of reasons, but not because we didn’t love our coach.

The Big 3 were:
1. Wet bay floor: fixes were replacement of the floor material and the addition of additional support structure to prevent sagging.

2. Driver's side slide floor: Repair to coaches affected were replacement and recaulking of the floor structure. Front slide was removed to fix the floor.

3. Cracked roof rails: Attempts to use an all fiberglass roof resulted in cracks developing in the curved portion (the rail) of the roof. Units affected were repaired by replacing the fiberglass with metal. Corrected in late 2012.

Tiffin can verify these repairs by VIN number so if you are looking at 2012 and earlier models be sure and check. Wet bay is easy to check - just look underneath the coach. If the wet bay floor is plastic and not sagging, you are fine. Front slide floors were a short term manufacturing problem that was corrected mid-year. Roof rails, if not replaced, will have what looks like cat scratches running from the top of the roof to the bottom.

Personally, I would stick with the 2013 - 2015 models.

FYI - Mine is a early 2011 40' Bus with Powerglide Chassis and the following are original not corrected:

PS kitchen floor is the metal frame vs plywood.

Water bay is the plastic with additional supports.

It does have DEF.

Switches are multiplex but not spyder or maybe an early version.

AquaHot 450 D


I would recommend buying the newest that will fit your budget simply due to aging of all systems. If like many here and you do your own work then the options are greater.

Other considerations for all years in a used motorhome besides engine & tranny:

Tire age
Slide Toppers
Awning fabric for patio & windows
Shocks
Roof Condition
Slide Operation & Condition
Look for rodent damage

Hope you find a gem and enjoy the adventure
