Its not just you with that opinion. Even big rig owner operators and small semi fleets are buying “new” semis that are basically 2/3 new, then getting old transplanted engines like the ol series 60 detroit ddec back in the mid 90’sof course rebuilt completely for reliability. Glider or Gliding is the term iirc. They are not allowed to drive California, but everywhere else. Breakdown time is less, support is easier found anywhere, repair costs are less, even allowed to still use paper log books still.

Seems to me that the marketing bar to beat is Ferd's 150. Weight rating is up to 18,100# GCWR for 2019.
Well lets talk about the Ford F150 a minute. Yesterday I saw one towing a 30 some foot bumper pull camper and the poor F150 looked like a 747 taking off. I swear it looked like the rear bumper was about to drag the ground. The guy was with two other campers and trucks, I know one of the other ones was a nice looking Chevy Avalanche. The Chevy was towing a pretty good sized camper also but it didn't appear to be squatted down as much. The third truck might have been a 3/4 ton truck and camper, heck I couldn't take my eyes off of that poor F150.

I know the direction those guys was traveling, in about 12 miles they were about to encounter an eight percent grade (climb) with about a 7 percent grade going down hill on the other side. I have pulled campers across that mountain before, I wouldn't have been driving that F150 for anything. :nailbiting:

It all boils down to some people thinking since their truck has a powerful Eco Boost engine that it will man handle a big camper that a 3/4 or ton truck should be towing.

Definitely not arguing practicality of whether some people know how to load the weight . . . If that 150 was a bumper pull and squatting, was more likely a driver issue than the vehicle and, given the description, a lack of a WD hitch appears likely. Depending on the age of the 150, the older ones are true 1/2 tons where the current generations are more capable. As a comparison, my current tow vehicle pulls that length RV with an IRS / struts and has zero squat. Combined is ~15K#. Naturally, a weight distribution hitch in my rig plays a large part in the lack of squat.

FWIW, that Avalanche was available in a 3/4 ton suspension which might explain its appearance with the trailer in tow. Or it could have had a 1/2 ton suspension with a WD hitch.


The point of the discussion is that I have no confidence that GM marketing team will avoid going down the 'we-gotta-up-our-numbers-to-one-up-the-competition' path either. And, am sure that they will have the Legal folks work to back-up the marketing claim with some limited-scope engineering test that was executed in ideal conditions ;)


So, Yes, the marketing target to beat is 18.1K# and I have confidence that GM will work to get there no matter how limited the test scenario . . . Operator intelligence is a completely different topic . . .
