Re: Long Hauls
I looked over the suggestions for your trip and agree with most of them. However I would like to make a couple suggestions and an observation.
If you are pulling a trailer with a gross weight of 3000 lbs or more, and I think you are, then you should legally have brakes on each axle of the trailer, in most states. You don't say where you will be going but you should make a point of researching all the trailer laws of the states you will be traveling thru as some states are more aggressive than others in enforcement. (Case in point N.C. is reported to be very aggressive, and have been known to refuse to let travelers continue their tow when not in compliance.)
Get an infared temperature guage (from Harbor Freight $20.00) to check your hub temperatures. Check the temperatures everytime you stop for gas, food, sleep, or whatever and be sure to watch for changes. My hubs run between 108 and 112 deg. Check yours often and you may forestall a breakdown.
More important, you wont BURN YOUR HAND!! A bad hub can get really hot and will burn you before you can react.
Do carry 2 spare tires on rims, 2 complete sets of bearings and at least 1 replacement hub. Carry the grease, both gun and can, rags, and a really good jack,and maybe a couple short 2x6's to go under them.
Also, travel with the plug out of the boat. Take off the prop, remove any electronics not built in and all loose items in and on the boat, even the batteries. Get really good locks for the hitch and receiver, even a "wheel lock or boot" that will keep the trailer from moving if taken off the truck. And park under the lights, in a busy parking lot, where you can see it.
None of this will keep someone from stealing your boat if they are determined, but may make them decide to try some one else's boat if they are opportunity thieves.
Keep your speed at 60 mph, you will get better mpg, and some states require it.
And yes, you should have a transmisson cooler, as well as a tow package on the truck. If you do then tow in the "tow/haul" mode.
Good luck,
Bob
