Thanks for the replies. I have heard towing a 5er is much less stressful than a bumper pull trailer. I started pulling our 32ft overall length trailer with a 1/2 ton pickup then decided to buy the 350 after a few months of owning the trailer. I never really liked the towing experience with that F150. I thought I had bought a big enough truck for a much bigger trailer. I have heard now that I need a dually for this particular 5er mentioned above. We see folks dragging around giant toy haulers with 250's all the time, not to say it's safe. Just wanted opinions from folks that do have bigger 5ers and tow with SRW 350s. Thanks again.
