Six Pack - once again. We are on the first week of our next 8 weeks in our 351DS. I've said this before but I gotta say it again. WOW - I made the Cheap Handling Fix and inflated the tires to 92PSI a few weeks back and today after driving about 230 miles on interstate at about 65-70 MPH, pulling our '13 Explorer with high winds, all sorts of tractor trailers - easy peasy!!!
The V10 never strained - no wanders - not much suck and push from the tractor trailers - a real easy drive. We paid $2.03 for gas, got about 7-8 mpg it isn't a pusher but it cost a LOT less to operate and drive easy.
The 335 is the same chassis but the box is about a foot shorter.
US Army - Retired and loving it with our Georgetown 351DS and now our Thor Challenger 37TB.
