You probably mean a "tow rating" of #9500... Look at the PAYLOAD sticker on the truck and that's really what you can handle payload wise.. This is probably in the #1200-#1400 range and means that's all the weight you can ADD to the truck which includes additional passengers, stuff in the bed and most important, the tongue weight of the TT you hitch to it...
Those trailers you mention will likely have at least #800 TW to as much as #1200 once you get it loaded up... "Dry weights" for TT's and comparing that to the "tow rating" of your truck is usually a recipe for being overloaded on the truck... How much that overloads it and what your towing experience is is up to you to determine...
Most of us "seasoned" RVer's have learned this over the years by experience and more than likely, towing overloaded before and knowing what that's like! ;)
Good luck!
