Truck towing capacity

[banjoguync]

Ok, so me and my family (wife and 3 sons) are considering buying a 5th wheel trailer and need some info as far as what to look for in weight. I have a 05 Ford F350 Lariat 6.0L V8 Diesel dually and loaded with us and our stuff about 1000lbs extra.....Im new to this and while I found this site I don't know how to make sense of it. Its a Crewcab 4x2

Can anyone help me, what weight should I be looking at for a 5th wheel without going to heavy? Id like to go low to be honest

You should look at trailers that fit your needs and budget first. Bigger is not always better. There are many facets to towing including payload capacity,rear gear ratio, GVWR and rear axle rating. The version of truck you have has been known to experience engine problems also. Has yours been reliable? Your going to have to learn these and what they mean, there's a lot of homework to do but we can help. What's the GVWR of your truck and how much does it weigh to start?
