Not sure what you get for gas mileage but only 175 mile on a tank is .....awful!!!
I've heard that the Rams suck at MPG!
I get 11 MPG with my F250 SD Diesel when pulling. That gives me 330 on a 35gal tank. I always try to stop and refill between 1/2 and 1/4 tank.
The funny thing is, F250,350,450, they all have the 6.7L diesel engine. It is a work horse at 1075 lbs or torque and 475 horsepower.
I agree with the above statements. If you can go bigger. A 350 or 450 would be ideal. I will however disagree with the DRW. I have not had any stabilization problems with SRW on my F250. Not real sure what the sale price difference of the larger truck is however.
The problem is, you have a 5th wheel so that you can disconnect and go see the sights. You will be able to park in a normal parking spot with a SRW truck but a DRW? Not so much. Just going thru a drive thru I have to watch close, but doable, with a SRW, DRW, don't think it would be possible. If you like disconnecting and going into town or doing trips, it is something to think about. Not convinced a DRW is a requirement. I;m sure it might be a better ride but the inconvenience of the DRW would not be for me!
I'm not trying to talk you into a dually. But just know I drive my dually all day everyday. It is not just my tow vehicle.
I drive thru 2 different bank drive thrus regularly. Some drive thrus are too tight but most I can get in
I go to big box stores all over town and have no issues parking. The parking issues occur with multi level parking lots.
Small towns and urban areas can be tough parks but that is more due to length than width. My dually is no wider than your SRW mirrors.
I challenge you to find a spot where your SRW will fit and my dually won't. It's length that's the issue not the hips!
Lastly and this is the "A Ha" moment that you can only experience first hand.
You are totally comfortable with your SRW, however you cannot fathom the dually towing improvement until you tow with the dually.
The handling and braking improvement will change your perspective on the SRW truck.
The bigger the trailer the bigger the more noticable the improvement. Again I'm not suggesting you need a Dually I have no idea of your towing parameters.
But I am confident if you were to tow your current rig with a dually you would notice an improvement.
If you never drank milk it would be hard compare it to water without trying it.
Many draw conclusions about duallies that are not based on first hand experience.
Much like driving a diesel vs. a gas engine its that in person first hand experience that is revealing and game changing.
My comments are not really to change anyone's mind.
But I do want to state that the towing improvement of a dually is real and not imagined.
If you are content with a SRW that's totally fine. If you are looking for improvement a dually will provide it.
