In general it is a bad idea to tow a fiver with a half ton. As mentioned above the payload is a big problem and the other issue is brakes. The manufacturers and rv salesmen will tell you you can, but once the papers are signed and the fiver is off the lot they don't care what happens. They have their money.
There are many 5ers that are light. My 34' weighs in at 8500# I have a friend that pulls a low profile Coachman with a Ford Ranger. Everybody told him it couldn't be done with a Ranger. His response was that he sure was glad he has done it over 10 years before some expert told him it can't be done. If your friend is truly interested maybe have someone pull it to a platform scale and weigh it with the trailer and back axle of the truck and then drop trailer on scale. You will be able to figure pin weight and total weight of the unit.
