The Owner’s Guide for our 2010 Ford E450 with a V10 says extensive break-in is not necessary, but to vary speeds for the first 1000 miles. However, it also recommends not towing for the first 1000 miles.
Can someone explain to me the difference between towing with a V10-equipped pickup or van, and normal driving with a V10-equipped 12,000 pound motorhome? It appears to me that all those Class C’s and Class A’s with V10’s were driven with a load from the first day, and very few have engine problems. I would guess that most were not driven very gently during their delivery from the manufacturer to the dealer.
