We have towed with our 1998 E350 cross country with no issues. We are a family of 10 (2 adults and 8 children), so we have very limited options for a tow vehicle. We come close to 10K fully loaded complete with bicycles for everyone loaded in the TT. Only time we had a "challenge" was driving up the grade from El Centro (Ocotillo) towards San Diego on I8. We were in a race up the hill against an 18 wheeler. Kids cheering on and the truck driver waving at them. Memories.... We now have a 2007 but still have the '98 around for emergencies.
