These trucks tow better than any other gas-powered truck or SUV IMHO. I've towed the Mastercraft (approx 5500 lbs overall with 500lbs tounge weight and 30' on the trailer) with Yukon Denali, Surburbans, other PU's, a Lexus LX470 and the ultimate - Raptor. The Raptor's width makes it totally stable even in heavy crosswinds or rain slick roads. Torque is ample. Fuel economy is better than all the others for me (best I got with the others was 11mpg, now I get 12 at 65mph. Some tips I've learned the hard way - take em or leave em:
I like 4-flat plugs best personally and blow right by the round plugs, I've have had nothing but trouble with them....others may swear by them.
Don't plug the boat trailer lights in when the truck lights are on, you will probably blow the 20 amp fuse (#73) feeding the trailer light relay. Familiarize yourself with the fuse box. I unplug lights before dipping the boat. Carry spare brake/turn light bulb.
Roger on "trailer backing up parking lot training/practice" - also, think about who is going to drive boat or truck. You and your other driver need to practice both. Might just save your marriage one day....I am always so proud when my wife and/or daughter jumps out of the boat and runs to get the truck and backs right down the ramp....other guys just stare in amazement. Don't be those guys who stare.
I repack my trailer bearings yearly no matter what. It's not at all hard to do, just takes about 20-30 minutes per wheel. You DO NOT want to shell a trailer bearing on the road, it will ruin a whole weekend, I've done it. Even if the wheel doesnt come off the axle and pass you on the freeway, the bearing failure usually takes the axle shaft with it, then you are looking for both the bearings and an axle to get welded on. Carry and extra set of bearings with you and some grease and a cap. When you stop to let your passengers pee, check the bearings, warm to pretty warm - ok, hot to "it burnt my MF'ing finger" - not good at all - roadside repack/repair called for. I used to use bearing buddies, no more, once they heated up, I would sling them off leaving the bearing exposed...not good.
My trailer has surge brakes, I love em.
Unless your boat cover is made for the road, pull it off. If you don't, the wind will.
Don't forget the plug.
I top off my boat battery and hit the starter in the driveway before I get to the ramp...nothing worse than hearing the click...click...click of a dead battery. I also keep cables in my boat just in case I have problems on the water.
Finally, towing/launching/retrieving a boat is all about forumlating a process, a written or mental checklist and repeating it every time you go out. Do just a few easy things right, and you will enjoy every outing. IJS
By the way, that is one beautiful fishing rig!!!
