Title: Tiffin 2008 Fred towing
Post by: Juliemom28 on January 23, 2020, 09:47:23 PM
Hey guys, this is my first post on this forum, so hello!  We are not new to RV-ing.  We bought a used 2008 Tiffin Allegro Bay 35QBA FRED 6 years ago with very low miles.  Up to this point weve used it for vacation 2 to 3 times a year.  We really like it, but are looking to upgrade in the next 2 to 3 years. This summer however, we are planning a four week trip out west.  Yeah!  We have never towed anything with it, but we might like to on this trip. I am having the hardest time finding out what the towing capacity is. Is this a set thing or something we have to figure out on our own based on the weight of the motor home, etc?  Thanks!

Julie

According to this, it is 5000#.  Sounds typical from what I see on this forum.  Others will chime in, and you certainly can search around for best toads and set-ups to tow them.

The max safe towing limit is determined by the lesser of a couple things. One is the rating of the hitch receiver and its attachment to the frame; another is the GCWR (Gross Combined Weight Rating).   The chassis limit is the difference between the actual loaded weight of the motorhome and its GCWR.
Freightliner shows the GCWR of the MC Chassis (aka "FRED") as 30,000 lbs and the GVWR as 26,000 lbs.   If the coach actual weight reaches its 26,000 lb max, then towing would be limited to 4,000 lbs  (30,000 - 26,000 = 4,000). However, if the coach actually weighed less, say 24,000 lbs, then the chassis could tow more, i.e. 30,000 - 24,000 = 6,000).

I did not find a statement from Tiffin about the receiver rating, but I'm fairly confident it will be 5000 lbs, which is pretty much standard on this class of motorhome.  That would mean the most that ever could be towed would be 5,000 lbs but that might decrease to 4,000 if the actual loaded weight exceed 25,000 lbs.

Thanks guys!  Does it make a difference if its an Open Road, not Bay? Thanks again!

Yes, it makes a difference.  The Allegro Open Road uses the Freightliner MC chassis with a 26,000 lb GCWR instead of the 30,000 lb GCWR.  That's because the transmission model is different (Allison 2200). Here are the chassis specs for that chassis:

And the Allegro spec sheet and brochure:

The lower GCWR is likely to cut deeply into the towing capacity. Your best bet is to load up the coach as you would normally travel and drive it to a truck scale for an actual weight. You can tow the difference between the actual weight and the 26,000 lb GCWR.
