SRW vs DRW

Good morning everyone hope your all doing well, So just recently we built a home off of a lake we used to camp at regularly, by doing that we've cut our camping in maybe half.... we spend our usual 1 month trip up at our favorite lake every year though, so our towing needs has decreased significantly, so i actually got rid of our 2015 ram 3500 limited drw about 2 years ago now just because i couldnt justify it carrying my butt around 90% of the year as a grocery getter. So for last two years ive been using the welding truck to pull our rig to the lake 2007 5.9 quad cab, with G56. The truck handles the load perfectly fine, its no rocket ship but it does quite well, on a side note the reverse gear on the G56 is HORRIBLE, your either riding the clutch the whole time or are a race car driver, geared way to high.

Anyway, the welding truck isnt horribly family friendly with the quad cab, and looking into weather or not a SRW 3500 would actually fill our needs accordingly, more comfortable for the family, easier daily driver, and a little more justifiable to own than a dually year round as my personal vehicle. Our situation is a bit different and i am not sure how to read it. We pull our camper and boat in tandem and here are the specs.


2018 montana 305RL - 14,270LBS loaded weight, 2395lbs pin weight

19FT crestliner sportfish - 3800LBS loaded weight/trailer, 300LBS tounge weight. on a tandem axle trailer, 23FT overall length


so with these numbers gets us in around that 18,000LBS total mark. However if i just had the fifth wheel a SRW 3500 should handle that without issue.... ive always thought of the boat as dead weight when in actuality its just rolling resistance of course until your stopping. Would i be correct to say that just adding the toungne weight of the boat to the camper weight, and maybe even 1000lbs extra for rolling resistance, would have me still safely within a SRW 3500 towing capacity?

all in all our main focus is to just acquire somthing more practical to own year round, and not have to use the welding truck to haul the rig up to the lake. Personal vehicle at the moment is a laramie eco diesel which is an amazing commuter, but i do miss my 6.7

  • I may have missed it, but how far are you pulling this combination? That would be part of the criteria for me.
  • Only reason i am considering this is ive driven duallies as daily drivers for well over a decade now, just recently got the 1/2 ton eco diesel. In reality the dually is no big deal to drive around, but is absolutely over kill for 95% of the year and i suppose really a 3500 srw would be as well, but it would be i think a far more reasonable vehicle to daily drive in comfort and still have somthing to pull our camper around... kind of a compensation on either side of the scale. And really, i love my 5.9 but the old dodge cabs arent terribly family friendly especially the quad cab.

    and in all honesty the braking cant be any worse on a 18 and up 3500 SRW compared to my 07 5.9, thank god that thing has a super agressive engine brake and a standard trans.

    as for the boat yep it has garbage hydraulic brakes, i think they worked for about the first month of ownership.
  • I agree that the " NUMBERS" look to be good for a SRW, BUT . . . The Braking would/Could be an issue...

    Upgrade the RV to Disc Brakes and I think that would be a great insurance policy...
  • Yea me and a friend did some numbers last night of what we might be looking at for instance:

    2018 ram 3500 SRW mega cab with aisin
    payload: 4,060LBs if i remember right
    Max tow: 16,600LBS

    so to me that would be tons of payload even with two adults, two kids. And would sufficiently handle the camper itself. Also have a buddy that owns a high end diesel performance shop, if i remember him telling me correctly a 2018 ram 3500 srw and drw have same brake package and axle, the only difference is the two extra wheels, and spring pack
  • Looks a little light on pin weight but if it pulls well, I wouldn't worry too much about it and it does favor a lighter duty truck.

    Yanking on 18,000lb, that's definitely diesel territory.

    Does the boat trailer have brakes and do they work?

    What exactly do you expect to gain going SRW vs DRW? Both will love to hang out at fuel pumps and both will have a stiff ride. Cost difference should be negligible on a new truck (or even newer truck).
  • Your right that is a little different scenario.
    I'm more or less OK with the SRW for what you are proposing however 18K combined becomes a lot of weight for the SRW to stop....Especially a panic stop.
    In the end the main reason to get a dually is for the additional braking power.
  • The payload rating of the truck is always the important thing to look at. If the payload rating of the truck exceeds the pin weight of the trailer and the "stuff" you carry in the truck, then the SRW is all you need. Payload ratings of any truck, SRW or DRW, varies a lot depending on configuration; cab, bed, engine, drive train, even wheels/tire size.

    The boat does not add to the 5er pin weight. In fact, it will actually reduce the pin weight some amount since that weight is sitting on the back of the 5er.

    Do your homework on numbers.
