Are the single rear wheel cab/chassis out yet? I have seen a bunch of drw but no singles yet. Maybe luke can chime in and let me know.

 

They are available, just nobody seems to keep them. I haven't ordered one yet. Kind of an odd ball rig, and most likely the guy who wants a SRW will want it pretty specialized so it is best to just order one instead of keeping the wrong thing on hand.

 

My thought is to get a SRW and put a standard bed on it. I like the things I hear about the Aisan and think the lower HP may help mileage a little. I do not know hao much work would be involved in putting a pickup bed on a C/C. I will wait another year on the trade though.
On the fleet sites, tho only restriction on SRW is in combonation with the Heavy duty front spring option.
