I just have a couple of questions for you guys out there who I'm sure know more about this topic than I do. I currently have a 1990 Chevy S-10 4.3l v6 4x4. I use it to tow a small 4x8 trailer that I put my 36" Grevely walk-behind on as well as a trim mower. Right now, I'm just using the bumper hitch on the truck to pull the trailer which seems to work just fine. I am considering upgrading to a 6x12 or 6.5x12 trailer for next year which i would use to haul the same equipment on. Do you think I should also invest in getting a hitch installed on my truck if i get the bigger trailer? Thanks for you help!
