Trailer or Roof Top

[bmartin]

As for MPG, if it has a 'drive on gate' on the rear, you will get noticable drag that will probably negate the benefits of having a clean roof top. Also if the chevy axle of the trailer includes the differential and has to turn the pinion gears constantly, the trailer will also eat into the MPG more than other trailer designs. Either of these factors might make it a wash compared to roof top boat transport if MPG is the only factor.

In the end though, if you have room to store it, it is a no brainer at that price IMO. Tread life is less a factor on trailers than the age of the tire and would hunt for a couple of used tires. You should be able to find decent used tires for $20-$30 and get a used rim for another $20-$30 for a spare. Having a trailer opens up options in terms of the people and gear you can pool together and offers many convenience beyond boat hauling. Kind of like getting the benefits of a full size pick up when you need it.

Ouch, I didn't even think about the axle turning the differential.
That will definitely contribute to the rolling resistance.
Well, with boats and all on top of the rig, I get a steady 13 MPG. from what I have seen. It may be more (or less) but overall it's looking like 6 tanks of gas for the trip out to Nanty/Ocoee and back. 21 gallon tank... gas is about $3.60 average. You do the math.
I am still going to take a look at fixing the trailer... Ryan... for $30 you can tow it if ya like!
