Anyone towing with the 6.4L RAM Gas

Just curious if anyone has either the 2500 or 3500 6.4L to tow a 5er? If so what are the plus and minuses? Gear ratio, weight towed etc., would be helpful.

I have a Mega Cab 2500 Big Horn with the 6.4 and 4.10 gears. The reason I went with the 6.4 is:
1. It was a 2015 model after the 2016's came out and the dealer had it 10K off sticker and gave me the million mile warranty at a hugely discounted price.

2. The option for the diesel is about 8K over the 6.4. Diesel is running about 25 cents higher than gas and you need to figure in that DEF fluid. Maintenance costs on the diesel are much higher.

3, On a 2500 the cargo capacity with the 6.4 and 4.10 gears is a little under 1,000 lbs more than the diesel package. The diesel only has a 1900 lb cargo capacity.

4. I tow very little. I take maybe 6-7 short trips a year. this may change once the wife retires and we get a 5'er.

I don't have a 5'er yet. I still do tow my 31' 8,000 lb TT though. It tows great. Lots of power.

All that said:

The 2500 is an odd vehicle. The only difference between it and the 3500 SRW is the rear axle spring rate. They use the same components, axles, tires, brakes ETC. Of course the 3500 has leaf springs instead of coils. Because of this a 3500 has a approximate 1500lb more cargo capacity. Now, if you got a 2500 with the coils, not the air suspension like I have, and added air lift bags you could actually do as well as a 3500, not within the parameters of the factory listed cargo capacity, but you could do it.

On a 2500 Mega cab the best you can do for cargo capacity is 2900 lbs with a gas engine. At 2900 lbs you get real limited on what 5th wheel you can get. You'd be looking at units with a gross weight of under 11-12K lbs and even then you are pushing it. If you stay within the factory listed weight parameters I'd think there are very few fifth wheel trailers you could tow with the diesel.

Comparing apples to apples and oranges to oranges the 3500 with leaf springs is a better tow truck. Price wise only a couple hundred more. And a 3500 diesel with the Aisin trans even with the stupid 3.42 gear ratio will run circles around the 6.4. If you plan on towing much go this way. It'll be another $8,000-$10,000 in costs and you'll pay more at the pump but overall your fuel costs will be close to the same.

Once the wifey finally quits working I may get a 3500 CTD. I still refuse a dually as I just can't live with it.

BTW, if you go 2500, don't get the auto level. I really like it, but it has certain limitations I regret.
