SRW or DRW?

[welsteach]

Considering tc that weighs roughly 3800 dry. Would a 1 ton single rear axle be okay or do I need to look at double axle only. Please, no truck brand wars. Stick to axles. Thanks.

Go with a dually. My Truck Camper a 2003 Lance 1161 dry weight 3919 lbs. E rated and/or higher rated tires, Torklift frame mounted tie downs. Possibly air bag suspension, definitely make sure of OEM truck camper package installed. If purchasing a truck obtain a build sheet from the truck manufacturer. Also weigh truck before installing the camper. Take a look at Truck Camper Magazine helpful advice.

It doesn't matter how good of a driver you are, a DRW is not a kei car - Some of these cars are as short as a DRW is wide and would fit in the bed between the wheel wells.

It's also not a trail crawler or parking garage sized. There are appropriate vehicles for different conditions and just because a vehicle can go somewhere, does not mean it belongs there.

Maybe you could share the drw owners secret handshake that makes drws not as wide as they are when you want them to be smaller. 😉 Somehow, my drw didn't come with those instructions. Instead, it appears to be a fixed width all of the time. Sometimes it works for me, other times, not!

Any way you look at it, my CrewCab DRW is a lot bigger than my previous SuperCab SRW.

I totally agree! I've owned my dually for 11 years now and still love driving it and it still looks tough too. Also no banged up rear fenders here.
Ordering 19.5's for it also in a week or so....done with the 16's and a heavy camper.

As you have not purchased the camper or the truck yet you may want to consider a lighter camper. I knew I did not want a DRW truck for many reasons - width or truck, turning radius, length of truck, no double cab unless a long bed.

I decided that the maximum loaded weight was 4500 lbs. with SRW and that meant a 3500 lb. dry weight for the camper. Every pound lighter the camper the more of a safety margin and the more potential for carrying gear or a generator and fuel. There is also the need to consider the tongue weight of a trailer should you later want to tow one behind the truck.

I found that the Lance factory weight as shown on the camper was 300 lbs. more than indicated in the brochure and the actual weight at a CAT scale was 300 lbs. more. That was before putting fresh water in the tank at 8 lb a gallon.

There are many excellent campers for short bed and long bed trucks, even with a slide-out, that weigh under 3400 lbs. dry weight and can be hauled around in a SRW truck. If I was going for one of the very large dry bath campers that required a DRW truck I would go with a Class C motorhome instead and have a better integrated RV and a much less expensive one.

With the MH you only need to fuel up and load up. With the slide-in camper and pickup truck you become the system integrator and deal with load data and what to do to modify your truck (tie-downs, electrical harness, fuse and isolator, bed liner, shocks, anti-sway bar, tires). For a smaller and more nimble RV I went with a SRW shortbed 4WD truck and with a smaller and lighter camper. But I travel 100% in the west and on forest service roads and not on the interstates going from one RV park to the next so it all depends on the individuals and their spouses.

Many of time that is the case, as the hips are narrower than the mirrors.

There are plenty of back roads, around here at least, that are limited to SRW only. Tight and rocky corners where the SRW's barely fit come to mind.

DRW's are also a PITA to grab anything out of the bed from the side relative to a SRW, and I am 6'4" with a good reach.

In our area "standard" parking spots are 20x8 and "compact" are 16x7. You will see more of these compact spaces as business meet the zoning guidelines with less parking surface area.

To date, I have found only one limit: The parking spaces at my new job. They are not wide enough for an SRW pickup truck, let alone a dually. Literally. I don't know what idiot painted the lines on this parking lot, but there's only about 4" of clearance on each side with my SRW daily driver. Even the compact cars are squeezed for space.

The SRW 19.5's are great, I haven't regretted them once yet. Stable, smooth, and just feel like a better tire. I am glass smooth up to 73, and start to get a slight (really slight) vib at 74-75 that is about the same thru 80 (as fast as I have had them since they have a 75 mph rating). I am not sure if it's tires, driveline, or both.. but the road condition makes it worse. A smooth new road is smooth as glass at 75.

A DRW would help with weight, but I do too much driving on roads where a DRW would be a poor choice.

+1 🙂

The 3rd gen's are even worse. The front axle for a 2500 Hemi is the same as a DRW CTD, 5200lbs from 03-09.

The lightest I have ever seen my front axle is 4750, which ironically was the heaviest the GVW has been at 12090. I had enough weight behind the rear axle the front got a bit lighter.

With 6 people in the cab and a trailer hooked up I was at 5340 last month, it would have been around 5500 without a trailer.

Empty (normal gear in the tool box, about 400lbs), without a driver and full fuel I came in at 4950 last week.

It's one of the reasons I went to a spin free with bigger bearings, and better ball joints.

In 2010 it did increase to a 5500lbs axle, and as of 2013 the 3500's have a 6000lb front axle.

Okan,
At the time i bought the truck the determining factor for me was the higher spline count, bearing and RG&P upgrade, and larger axle diameter that they Just started putting on 3500's with the V-10 option in 2000 and only in 2001.5 to 2002 with the Cummins H.O. engine and NV5600 combo. No D70 parts anywhere to be seen. I know this for when I installed the Power Lok rr limited slip, they had to re drill the D-70 plate to fit the larger RG parts. These did not appear before that time, but were the 'detuned' versions you speak of. If it weren't so I certainly would not have plunked down my cash for a new truck that year. I have a friend with a 17K pound MoHo with a gas 454 and the self same Dana 80 to-the-max under the rear. His is rated at 13,500 pounds. He had a leaky pinion seal and had me crawl under there to see what was what. I got under there and lo and behold it looked exactly like the D80 under my rig. Of course, it's hard to tell unless you take it down to see if it's mostly Dana 70 air inside the pig.

http://en.wikipedia.org/wiki/Dana_80

Motorhomes and larger cab and chas trucks Dana 80`s have the 37 spline and 1.58 dia. axles same tubes , different length ,always always dually with larger wheel bearings.Different larger gawr
.
THe dana 80 and 70u in SRW have 35 spline 1.50 axles and the same hubs and brakes , pre 2001.5 drum brakes =2 1/2 " wide shoes , after same disc`s
DRW had 3 1/2 " shoes
On Pirate 4x4 forum , where they modify these axles , Ive heard the center section/ pumkin gives you the torque rating and the wheel bearings give you the Gawr

Ive been looking at putting a DRW Dana 80 on my 99 Dodge SRW truck,and front DRW hubs and dually spacers , mega cab dually flares like this

17" dually rims & tires ,and cab &chas 8 leaf spring packs, cost =4000.00 +

3800 dry on any SRW is on the bleeding edge even with mods. The question is how much do you want to carry with you as well. For some people, that's up to 1500 lbs. With my SRW, I was careful about what I brought along. My SRW had a GVWR of 11400.

As is always pointed out, it's easier to buy a newer DRW as long as a DRW isn't too limiting in other ways. Also, note not all DRWs from all years handle heavy loads the same. Older DRWs only have an advantage of more tires on the rear. Look into the GVWR of the DRW before assuming it will give a good ride and can stop. The gap between older ones and newer ones can be thousands of lbs.

There is always a tradeoff.

[mkirsch]

Regardless of whether the "dry" weight is a base camper, camper with options, it is still going to be well over 4000lbs loaded and ready to camp. Plus passengers.

4000lbs is my personal cutoff where I, under no circumstances, would recommend anything less than a dually. Under 4000lbs you can fudge the numbers and bolt on widgets and doodads and make it work, but there's a diminishing return on that as you get heavier, and need more and more addons.
