Is trailer weight or length more important?

So Iím looking at grand design trailers. Reflection 312bhts which is 9500 pounds dry and the imagine 3150bh which is roughly 7500 pounds dry. Both are around 35 feet long.

My question is this. Iím towing with a 2017 f150 ecoboost. Both trailers are within my ratings (the 312 reflection obviously pushing it). Will the weights have any effect on how much i get pushed around by wind? Like when tractor trailers pass. Am i off base by thinking the heavier the better when it comes to handling?

I'm pulling a fifth wheel so can't say from personal experience. But our neighbor / camping partners are pulling a 2150RB with an eco boost. It's 27' and 5300 lbs. dry. Think he has the better tow package cause has around 2300 lbs. payload per door sticker. He say it's about all he wants to deal with, especially in a cross wind. I don't see where more weight is going to offset the wind effects on that large of a surface area.

I don't believe either will be within your payload capacity.

I wouldn't tow either one of those with a 1/2 ton unless it was an F150 with the HDPP.
Both are too long and the 315 will have 1400 lbs on the receiver.
1/2 ton tow ratings need to be taken with a grain of salt. Most 1/2 tons don't have near the payload capacity to carry the tongue weight on long heavy TT's.

I use a 2013 F150 Platinum Screw 4x4 3.5 EB with Max Towing and 3.73 EL rear to pull a 31í overall, 6,500 lb. trip loaded trailer using a Blue Ox Sway Pro WDH. It handles great, but there is no way I would want to tow anything longer with a F150 class truck.

What is more stable a big guy carrying a tiny back pack or a little short guy carrying a huge backpack. Tow vehicle size compared to trailer size is very important unless there is no wind and no emergency steering needed. Both are hard to predict.

Didnít want to get into the tow vehicle debate. Iíve towed a same length travel trailer for a season with a less capable half ton with no problems.

Let me re word my question. If you have 2 trailers of the same length. Which trailer would be more stable on the road. A 9500 pound trailer or a 7500 pound trailer.

No, you're probably misinformed. They may be within your tow rating if you have nothing in the F-150 but a skinny driver, but both will exceed the payload capacity of your F-150 if your F-150 does not have the heavy duty payload package (HDPP).

The heavier one is out of the question. The lighter one with dry weight of 7,500 pounds will probably gross about 8,500 pounds when lightly loaded for an RV trip. 8,500 pound RV trailer will average 1,200 pounds hitch weight (1,100 pounds tongue weight plus 100 pounds for a good WD hitch).

Weigh your F-150 when loaded for towing, including a full tank of gas and all passengers, pets, tools, campfire wood and other weight that will be in it when towing. Subtract the weight of the wet and loaded F-150 from the GVWR of the F-150 and the answer is the payload capacity available for hitch weight. If the answer is not at least 1,200 pounds, then that's too heavy a trailer for your tow vehicle.

If your EcoBoost engine is the wonderful 3.5L V6, then you have plenty of power and torque to PULL an 8,500 pound TT, but not enough suspension to handle the hitch weight of that heavy a trailer unless your F-150 has the factory installed HDPP. If your engine is the 2.7L V6, then you probably don't have enough payload capacity to tow either of those trailers without being overloaded.

Don't think it is that simple...is the 9500 trlr 25 or 35 ft long? And is the 7500 25 or 35 long? Which one is better balanced as built?

And since you are quoting 'dry' weights, when you load either one--and how you load it--is going to have a big effect on stability.

You can use a better hitch (ProPride/Hensley) to help also.

Best listen to bfisher's comment in post #5, also the general trend of the rest of the posts...

Here are the specs. The first is of the imagine. It seems pretty balanced and a light tongue weight. I wouldnít worry about pulling this. I towed a same length Forrest river that was a about 1000 pounds lighter with a Chevy half ton. Second pic is of the reflection. It still has relatively light tongue weight compared to other trailers Iíve looked at.

Iíve looked hard at these. Would you be more comfortable pushing weight limits with one?

They have so many 5 star reviews with zero bad reviews. Makes you wonder if everyone raves about them because they just paid nearly $3000 for a hitch. Lol

Looking at the design it is pretty impressive.

Sorry for replies going off topic, including mine. Thinking logically it would seem the lighter would be better. You can load it with a higher percentage of tongue weight which should help sway. Any sway should also affect the truck less if standard laws of physics apply. Still think crosswind will be the issue.

Here is a simple video for ya. How you load the trailer is every bit as important if not MORE important than how much it weighs. That being said; Don't try to run at your trucks' max capacity and leave yourself some safety margin.

Here's some real world weight stickers for the Imagine and 312.
New 2018 Grand Design Imagine 3170BH Travel Trailer at Trailer Hitch RV | Nipomo, CA | #7879
New 2018 Grand Design Reflection 312BHTS Travel Trailer at Trailer Hitch RV | Nipomo, CA | #7691

As you can see Grand Designs brochure weights are fairly low compared to the delivered weight. I frequent GD's owner forum and it's common knowledge that their trailers are a lot heavier once delivered. Also the tongue weights are much heavier once delivered. Pretty much normal for any brand.
Both of these TT's are 37' long. Both will be over 9000 lbs loaded with tongue weights in the 1200-1500 lbs range.
Thats way too much for a 5000 lb truck to tow.
Instead of spending $3000 on a special hitch, and another $1,000 to upgrade the truck tires and probably another $300 on rear suspension mods or receiver hitch you be better off taking that money and use it to upgrade to a 3/4 ton truck.
You're always going to be behind the 8 ball with the TT's you're looking at.
JMHO but I feel that 7,000 lbs loaded and 30' is about the upper comfortable limit for most 1/2 tons.
