Title pretty much says it all.  Anybody have any good recommendations for a website, brand, etc for a good towable cover?

Aurora Canvas Battlefield MO.  They have been making custom covers for years.  I have one that is 9 years old, been all over central US and still going fine.

I bought a Bass Pro Exact Fit cover made specifically for my '02 Tracker Pro Team 175 in 2003 for the specific purpose of covering it while on the road as I moved between duty stations with the navy.  I've had it now for 8 years and it's still holding up pretty well.  Granted, I've kept my boat in the garage whenever possible so the cover had been primarily used on the road, but it has spent about the last year and a half outside in the Texas weather after I moved and didn't have room in my garage.  The fit was excellent around the gunnels, but I did have to add a 3 1/2' section of PVC pipe next to the console to "tent" the cover and keep water from pooling in it when it rained.  I've been pretty well pleased with it, especially having lasted as long as it has.

i bought a bps one and its really good, just dont use the straps that come with it.
