Thanks.

I owned an 01..don't know how long GM used the 8.1 ( they stopped using it because it wasn't MPG friendly).., which was a 496 cubic inch gasser, which was, originally, a 454, but had been revamped and ended up as a 496 CID Vortex V-8, i.e., 8.1 liter engine/with 4.10 gearing and the Allison transmission..It was the only gasser hooked to the Allison, other then the Duramax.

So if was build through 05?, 06?..I'm not sure, I Owned for D/A's after that.

according to GM, it was beefed up from a 454 to a 496 cubic inch displacement engine...Marine model may be 502 CID, but one I'm talking about, the 8.1 was 496...never met a filling station it didn't like..but it was a towing beast, and strapped to the Allison just made it amazing...

The engine started out as a 454, but bored out, bigger components boosted it to 496.

One liter = 61 cubic inches; thus 8.1 liters = 494.1 cu in, but it's a "tad" bigger than 8.1 liter...8.1 sounded better...no matter how you say it, it's a BIG BLOCK engine(:

Not set on Anything

I would highly suggest 3.73 gears and the Max Tow package if you can find it as this will up your payload and give you better cooling, etc.

I would suggest 2013 and up if going the EcoBoost route, as the '11 and '12 years had the odd bug to sort out like most new concepts freshly released. Mine has been flawless, for what it's worth.

Most of the newer half tons (last 3 years or so) have much higher capabilities than their predecessors, so with that trailer you should be able to find a good match pretty easily in any brand. A big help is the number of gears the transmission has - most have 6 or more these days and that makes a huge difference in towing performance.

As always with any half ton, WATCH YOUR PAYLOAD! That little yellow sticker on the inside of the driver's door has caused a lot of grief for uninformed truck owners that learn about it too late!
Not set on anything except appropriate tow capacity and payload.

Looked at a 2012 RAM 1500 Tradesman today. 5.7L HEMI and 3.92 rear end.
42K miles, very clean and easily in the budget. Much less than diesel and still will tug 10000#. So, will be comparing this to the 3.5L Ecoboost.

Believe I have narrowed it down some. Thanks for all the input and help.

As mentioned before watch the payload on the Ram 1500, it can be somewhat low on some models. We are not talking about the tow rating, but rather the payload which is how much weight the truck will bear on the hitch and cargo in the truck including passengers.

Sure are not too many MaxTow pkg EB on the market within 250 miles of me. Most are off-lease units with the 3.55 axle.
Have the word out with a couple of Ford dealers and watching Craigslist.
Time will tell..........

The 2011-2014 EcoBoost MaxTow came with 3.73 gears, and the 2011-2014 Heavy Duty Payload Package (different than MaxTow) was available with 4.10 gears.

In 2015 when they went to the aluminum body MaxTow came with 3.55 but I'm pretty sure 3.73 was also available.

Just because they went to aluminum and advertised better payload numbers in 2015, that doesn't mean any aluminum bodied truck is boasting great payloads. I was at the dealership the other day getting my truck serviced and I saw a '16 Limited with 1500lbs payload (200lbs less than my '13 XTR).

FWIW.. I bought a 2015 F150 XLT super crew w/ EB and max tow... payload sticker shows 1798 lbs.

The V-8's I looked at had significantly less payload.

3.55 Rear Axle Question

I have not been able to find one EB 3.73 rear end Max Tow used or new in nearly non-stop searching, calling and lot pounding.
Do find a fair number of EB 3.55 with Max Tow.

One such Super crew EB 3.55 with Max Tow and 7000# GVWR here that is of interest.Am I correct that this config has a payload of 2060# and a tow rating of somewhere between 10,600# to 11,500# (depending on GCWR)?

Thanks....
