I have had them all. I would definitely go with the dually. You can learn to drive it and the safety factor of the 4 rear wheels is worth the aggravation of the extra width

A Fool Proof Method for Judging Tow Capacity: Polk's formula

I've been scouring the forums, reading varied opinions regarding towing capacity. Many with half ton trucks are pulling RVs with a dry weigh of nearly 9,000 lbs; some even bragging about being able to do so. Being able to tow it does not mean it is safe to tow it. Dodge rates my Ram 1500 Quad Cab at 10,000 lbs. towing capacity. That does not mean I can hitch up a 9k pound RV and take off for a cross country trip!

Determining safe towing capacity of a vehicle can be confusing. Polk's Towing Capacity Formula is an easy, reliable formula to determine SAFE towing capacity. Using his formula, I determined it was not safe for me to pull a 9,000 pound RV even though my 1/2 ton Hemi equipped Ram Quad Cab truck is at the top in its class for torque, power and towing capacity. According to Polk's Formula, I can safely tow a dry weight of under 7,000 lbs. That leaves plenty of room for storage, passengers, etc. without having to fret too much about exceeding the capacity. Just my 2 cents.

It is actually quite easy: go to a scale and weigh your tow vehicle. Subtract GVWR from actual weight: that is how much you can carry.

To get more granular: subtract GAWR from actual axle weight. That is how much you can put on the axle.

Once you get close to one limit, you may be over on another. Just watch all of them.

Weigh, weigh, weigh. Easy peasy.

For some reason, people don't want to spend $10 to know the facts.

My formula is divide the OEM's tow rating by half. Just my opinion, I don't think you can have too much truck. Headwinds, grades etc...

1st is to check the number most likely to go over ~~ payload. Check the yellow sticker on the TV driver door pillar. A 9000# TT will have over 1000# on the hitch and a 5er 1650 or more.

Your method is clearly a very safe thing to do. Based on my VIN, Dodge rates my truck at 10,000 pounds. Using Polks formula, I come up with a safe towing dry weight of 6400 pounds.

Towing capacity and max load capacity are two very different things.

My general point is, IMO, MFG ratings are way too generous.

Max Tow is GCWR -Minus- Truck ready to go camping = MAX Towing Capacity.

Max Payload is GVWR -Minus- Truck ready to go campng = Max Payload Capacity.
