Front diesel engine

In my hunt for a motorhome I've come across a Tiffin Allegro 38tgb with a front cummins diesel. First front diesel engine I've seen.

Any concerns or issues with a front diesel I should know about?
  • Not too concerned about engine noise. Nothing can be louder than a downshiftikh ford v10
  • The older Safari Treks were built on the Isuzu truck chassis. Overhead bed in the front allowed them to keep the overall body length under 30'.
  • We have a front engine Monaco Vesta and really like it. Full air bag suspension, air brakes, etc...just like a DP. Only the Diesel is in the front.

    Yes it is noisier than a DP but does not bother us.
  • Not a noise problem with our's, 12 valve Cummin's is really quiet compared to my pick up with a 24 valve.

    There are actually quite few front engined diesel rigs out there. They were never real popular but they will get the job done. The ones that I have been in have sufficient sound proofing that the cockpit is not that noisy. Most DP owners feel that the front engine diesel will make as much noise as their engine does. They fail to realize that the sound proofing used on the front engine vehicles is not used on their DP so when they go back there, they hear everything. As far as diesel VEHICLES are concerned, there are many more with the diesel engine in the front than in the rear. The diesel pick-ups are very quiet when on the highway.
    I would not let noise be a negative if the rest of the coach meets your needs.

    Well said. Before you let anyone discourage you from a front engine diesel, drive one and see for yourself. You will also enjoy the extra 30 to 40 more HP that the front diesel is not using for the cooling fan, and running everything else to the front.

  • They are not popular for good reason. Noise is the big issue along with the loss of cabin space. Unless the unit is fwd the transmission and driveline take up a lot of useable basement storage.
  • I enjoy having my diesel about 35 feet away to make the drive much more quiet up front.
