For what it is worth here are my thought!
Getting others feedback on their experiences never hurts. Then again ignore the ones that simply say 3:42 gears are not enough, I wont pull anything with out a diesel and lastly the guy that can pull anything with his Honda!
Like others have commented - use the max trailer weight not the dry weight.
I run a 1/2 ton Chevy Silverado, 3:42 gears, 5.3L, and all of the towing options pulling a Jayco 23BHM that has a max weight of 6250lbs.
I try not to exceed 75% of the vehicle tow capacity.
Why 3:42 gears - there are in the middle, not stump pullers and not mileage gears! I can pull the mountains - I might not be able to blast up them at 65MPH but I can get up them!
I have towed at max capacity and for me it was not a comfortable experience.
Find a capacity calculator on-line. Run your own numbers and make up your own choices.
I found a calculator that calculated all of the capacities based on your particular circumstances. It told me that how many lbs I was under or over the manufactures weight limits.
Happy Camping 7 Safe travels!
