Nope. My 2.7 eco 145" Screw 4x4 with HD frame.
2016 standard tow package - no brake controller

 

Would you know the GVWR rating on your truck?

 

Interesting, 2018 5.0l , 4x4 sup-cab 6.5' bed. I occasionally haul a 1000lb truck camper in the bed, so nice that I have an HD frame

 

Joke of the week

 

I also have a 2.7 powered truck with an HD frame. 2016 Supercrew 145" WB 4x4 with towing package and brake controller. The charts seem to suggest I should have an LD frame.

 

I have a 2018, Screw, 4X4, 145", no tow package, 6600 GVWR, standard tow hitch, 2.7 Eco, 3.55 , 302a, 20" wheels, XLT power equipment group, chrome package..no other options at all, and my frame shows "HD", I thought for sure it was going to be a LD...
My truck is presently at the dealer, just bought it 2 days ago, dealer is doing an undercoat...had the dealer look at the sticker today for me..

 

I remember another frame thread a while back and we found that pretty much all 2.7s have the HD frame. Sad thing is the new Ranger has more payload than my f150.

 

 

I've got a 4x4, 3.5 eco, 145 wheel base supercrew with max tow and mine is listed as HDPP.

 

I have the same as you, 4x4, 3.5 eco, 145 wheel base supercrew with max tow and mine is listed as HD. I have an 2018 XLT,

if that might mean anything.
