I tow my 1986 31' Sovereign
with a 2004 Nissan Titan. Little less than 50000 miles over the last 7 years with no problems. My trailer in average trim weighs a tad less than 8000# (it has a 8600# max gross weight).
The only limiting factor is that I have to watch what I put in the pickup. With the bridal unit and me on board, I have about 400# left for "stuff" and you can reach that real fast if you bring all your tools, BBQ gear, beach tent, Mosler safe, bowling ball collection, generator...
I think your truck would safely pull anything other than the units that had slide outs (they are allegedly pretty heavy).
However, lots of Forum members swear by big honking diesels on 3/4 or 1 ton trucks for that "don't even know it's back there" feeling. Me, I like knowing it's back there.
By the way, 31' is a great length for tankage, closet space and stability.
