you'll end up spending a couple of thousand or more to get maybe 2 mpg, is it really worth it?

I get about 11-11.5 in the city on mine with the MDS on. I have a little over 3000 miles on it and it gets better each tank full of gas. I tried shutting the MDS off for about 1/2 tank of gas and the mileage went down to 9-9.5. Where I live we have a lot of big city streets with 45-50 mph speed limits. Long ways between lights sometimes as well. I use my cruise control all the time. I'm pretty happy with 11-11.5 in city on this big truck.

I have a 2015 RAM 2500 RWD 6.4L 3.73. I hoped that mpg would be better than a 4/4. I have never turned off MDS and believe that it improves the mpg by about 1 mpg. I think the sweet spot is 45 - 50 mph. I get 9.5 mpg towing 9000# 5th wheel. I get all around 13 - 13.5 mpg. And I can get 16 - 18 mpg cruising at 50 - 55. Cruising at 65 I get around 14 -15. In town the biggest problem is sitting at a light where it keeps gulping gas. At 65 MDS is on when going down hill or very light pedal and flat. At 55 MDS is on maybe 1/2 the time. At 45 MDS is on most of the time.

Definitely not looking to spend a couple thousand by any means but I'd spend a couple hundred on a muffler swap. With the miles I'm driving a 2 mpg gain would pay for itself fast. I'll keep and love this truck even if it gets 5 mpg but if a simple muffler swap would help it kind of makes sense at least to me.

There is one thing that greatly improves the mileage of these vehicles. Lie about it! Why? Because I'm tired of meeting other owners at gas stations and such that also have the 6.4 because of it's popularity and tell me their gas mileage is in the mid - 20's.
I just look back at them and tell them my mileage sucks and they get all offended. That reaction proves it's all BS they are spewing. I realistically get about 12 to 14 on a long trip and 9 MPG in everyday driving. Although, I may start lying like everyone else around here.

Amen brother! I don't know if their mileage figures come from the evic or they pick them out of the air but which ever way they are far from accurate. The best I have seen, figured the old fashioned way, is about 15.5 MPG driving 65 or under with no head wind.

Using my calculator The last 2 tanks I averaged 11.2. Probably 90% of that was city driving but to be fair we have a lot of long thoroughfares with 45-50 mph limits. I always use my cruise control and set it at the speed limit. Once I leave a stop light I hit resume and get back to speed as soon as I get to 20-25 MPH.
I ran 2 tanks of gas with the MDS off for the most part. Again I used the cruise control. Those tanks ran 9.6 MPG which to me disproves Chrysler is helping OPEC by putting MDS on the truck.
I have only done one good freeway trip and that was when the truck was new. 350 miles each way with a lot of hills up and down. Going I did 18.6 with the cruise on 70 MPH. On the way home, same route, I had heavy head winds and bad traffic in a couple places. That mileage dropped to 15.2. If your EVIC thingie isn't reading you have about 350 miles to empty when you fill up you are driving too hard. Towing a 8500 lb travel trailer in tow/haul mode I get right at 10 MPG. That is about the same as my '09 1500 did, but I tow the trailer faster with the 2500.
When I dropped the dollars on this truck I knew the mileage would really drop from what I got on my '09 1500 5,7 CC. That truck did a constant 12.5-13.5 in city and best of 22 on long freeway runs at 70MPH. So I figure if I can average for the long term 10-11 city and 15-16 highway I am more than pleased. I can remember years ago I had a buddy with a mid 70's 250 Power Wagon with the 440 in it. He never averaged more than 8-9 MPG in that hog. This 2015 truck has a lot more power and load capacity.

It's a Big Horn Mega cab actually. I did have a '75 1/2 ton Power Wagon. W100 short bed 318 auto 3.55 gears and it sure got worse mileage than this beast.
