FREDs have their place. Tiffin sells a ton of Allegro and Allegro Bay FREDS, although the new Allegro RED (rear engine diesel) is seriously putting a dent into the Allegro Bay sales.
Gas engines rev high and seem to accelerate faster than the FRED because oftheir horsepower. However, the FRED has more torque. You'll typically find that a gasser has more get up and go off the line butthat the FRED will hold it's speed on grades once moving better than the gassers and the engine won't be screaming at higfher revs. The diesel also gets better fuel economy than the gasser engines because it isn't revving as high and pump that much more air (and fuel) through it.
The FRED is a bridge. It's between a gasser and a diesel pusher. It's never going to replace either and it has it's bnenefits and drawbacks, just like everything else. It will all depend on what your friend is looking for. If it was me, I'd go with something like an Allegro FRED in the 34' range but if I wanted to go longer I'd go to the Allegro RED in the 36-38' range. I really don't feel that any front engine coach in the 37' range is the ideal solution because they are both minimal on power, torque, or both. Today's modern class As come with all of the bells and whistles and amenities that we are asking for and all of this just plain adds weight to the coach.
