Quick recap on my towing post from last week. The lake had fallen another foot since I was last there, and because the end of the ramp almost completely flattens out, I actually had the front tires about 15 feet down in the water in order to get the trailer deep enough for the boat. They had dumped medium size rock to stablize the ramp which got rid of the traction issue, but of course this had totally rutted out and had 8 inch or so pot holes everywhere and the entire middle section of the ramp is blocked off as too dangerous. I still had it in 4Hi, and if I wasn't sitting completely in the water, I would have switched to 4Lo, but it didn't seem like a good idea at the time to mess with switching when the waves are breaking over the running boards--just not a natural situation and not a time for something to not properly engage so I left it alone. The trailer axle bottomed out in one of those holes and I could feel the rocks scrapping the skid plates, but the truck kept on pulling the trailer on the frame until it popped loose and away we went up the hill, never over 2200 rpm. Although not a tremendous load (3500-3800 pounds), it was still a pleasant suprise to pull it straight out since it was like towing up a creek bed with all of the algae rocks and such. I still haven't had to tow in 4lo yet (knock on wood), and I'll save that for when the ramp is in REALLY bad shape (ha, ha). Just got word this morning that the ramp will be fixed for next year, so back to normal hopefully. Round trip was 366 miles, with 10 of that towing and idling for 21.56 mpg (actual, not computer). I guess I'll keep the V-6.
