Going to be purchasing a truck in the near future, and after that possibly a trailer or two. Is a 1500 grade truck (V-8) adequate to pull a 20 ft camper trailer? How about 8x16 enclosed utility trailer with 2 or 3 motorcycles inside? Or do I have to get a 2500?
I am not going to bother reading all the post because I am sure the majority of them are saying that you need a 3/4 ton diesel to tow that 5,000lb camper and that you should just get a 1-ton because it's only a little more and while your at it you might as well get a diesel. I swear it's an automatic response whenever these guys see the word TOW they think you need a 1-ton diesel, they are obviously driving the wrong trucks...

You want to tow a 20 ft camper? NO PROBLEM with a good V8 1/2-ton truck.
Here's a 27ft 7,700lb travel trailer I pull all over every other weekend with mine.

You want to tow an enclosed trailer? NO PROBLEM!
Here's my truck with the 8x16 v-nose snowmobile trailer that I use to haul our 3 Harley's to Daytona, Sturgis, Virginia, etc... I also put 3 snowmobiles in it and haul them to northern NH all winter long.

You want to tow a tractor or mini-excavator? NO PROBLEM!
One last picture, I haul my tractor to different sites all over for side jobs (3-5 times a month) and rent a mini-excavator when I need more digging power.

BTW, when I say a "good 1/2-ton truck" I mean any well equipped truck with the available towing package and largest V8 engine available. Watch the GVWR/GCWR, axle ratio and rated tow capacity of any truck you get.
