Grand Design 337rls reflection

Thank you everyone. We are going to order a new 2015 3500HD. I don't want to be tight on weight. Thanks again

If you get the 2500 gas, get a 4:10 rear in it.
You won't be sorry.

Hi, We just purchased two of the 337Rls models this week. If you need any info just ask, we have been over them with a fine tooth comb. My wife and I drive a 2011 Ford F350 4x4 SRW, our friends who bought the other unit drive a 2007 Chevy 2500 HD 4x4, On the trip back home we noted that due to the pin weight 2080lbs there was a little sag in the Chevy 2500 HD, the F350 had no issue. The driver of the Chevy will have air bags installed. Both of us are very satisfied with the units and both trucks will pull them, however the 2500 will be maxed out on pin weight. If you have not ordered the truck, I would suggest the 3500 for the additional weight capability at the pin location. The cost between the 2500 and 3500 is minimal. They both ride fine. The 337Rls has the axles a little farther aft which allows for better tracking but adds some pin weight ( the 303 model has a pin weight of about 400lbs less due to axle location a slightly less trailer weight). You will enjoy the model. good luck

I bought a 337 and took delivery of it 2nd week of December. I really like the floor plan, very spacious. My truck had zero problems the only time I pulled it, bringing it home. I have no concerns if my truck will handle my fifth wheel, I am certain it will. I am going to buy a truck this year anyway, but not because my current truck will struggle with this fiver, because I have been waiting on the 2015 2500HD.

Fm the Grand Design web site:
Model 337RLS
GVWR 13,995 lbs.
Dry Weight 10,698 lbs.
Hitch Weight 2090 lbs.
GCCC 3297 lbs
The Dry Hitch is 20% of the Dry weight, so if you take that same 20% of the GVWR you're looking at a pin of 2800 Lbs so you'll be pushing the limits of a 2500. The numbers are there, you just have to make the decision for yourself and family.

GM says the 2014 2500 Duramax with 2 wheel drive has a 5th wheel rating of 17,800 pounds and a payload of 3431 pounds. If you get the 4wd version it has a 5th wheel rating of 17,500 pounds and a payload of 3079 pounds. Your Reflection trailer has a gross weight rating of just under 14,000 pounds. The 2500HD Duramax will pull that trailer just fine.

My former truck was a 2009, 2500HD Duramax. Its 5th wheel rating was only 13,900 pounds but it pulled my 14,000 pound Everest all over the country just fine. We now have a 3500HD dually pulling the same trailer and I can't tell much difference over the 2500 except for the beefier Duramax.

Agree, get the 3500.

X2 this. The towing capabilities of a truck are essentially based on either what the truck can tow (pull) and what the truck can carry (weight). The salesman can very well be right when he says a 2500 can tow (pull) the trailer cause the truck's capability to do this is largely based on the drive train (eng, trans, etc.). BUT, usually the most limiting part of a trucks capability is what weight it can carry. For this you have to look at limits such as GVWR (Gross Vehicle Weight Rating), and front and rear axle weight ratings. As mentioned above, to determine a trucks ability to carry the load of a trailer hooked up you have to see if there's enough 'payload' which is the difference between the trucks GVWR and the actual weight of the truck, preferably weighed as it would be when going camping so it would include weights of all persons, pets, fuel, trailer hitch in bed, incidentals carried in the truck such as tools, firewood, whatever.
I know reading about all the different weights can really be confusing but it should be, IMO, a part of you must do to ensure you're towing safely for yourself and others.

Per GR website. 337RLS "Average Hitch Weight 2090lbs"
Per GM website. 2014 2500HD Duramax "Payload capacity 3079lbs"

The Payload capacity is not calculated after all passengers, gear and fuel are loaded. You must add up all those weights and subtract it from the "payload capacity".
1 gal of Diesel weighs 7.49lbs x 36 gal tank = 269.64 lbs
Fifth Wheel hitch weight (approx) = 150 lbs
DH + DW (approx) = 350 lbs

That only leaves you with 220 lbs of payload left to play with!

Throw in the Kids, the Dog, Chairs, Tool Box, and other stuff!

Too close for my blood!!!

The 3500HD payload capacity jumps to 3585 lbs. Much better IMO

Again, its not how much it can pull, but how much can it CARRY. Take your smartphone/calculator along with the GVW of the trailer and see if the pin weight is less that 20% if the trailer GVW.
