What gas mileage are you getting with Swift SLX series


Keeping in mind that the Swift SLX series of trailers are lower and more narrow than most, what advantage in gas mileage are you seeing.

My first pull with my 185RB with my Dodge Hemi was about 14. I was very happy with this but now the Dodge is gone and I have a Ford 5.4 SCAB. 4X4. I'm hoping that it will be about the same but time will tell. If there were no advantage in a lower profile trailer (ie gas mileage etc.) than why would anyone accept a smaller trailer? Just asking.

My neighbor went with the SLX. He is towing with an Explorer, and felt the smaller profile would be easier since most of it is hidden behind the tow vehicle. He also doesn't have much of a side yard, so the RV parking space is quite small. They were upgrading from a mid 90's PUP too, so in their minds, every TT offered a ton more space.

well for us, it was just down sizing from a 5th wheel. nothing to do w/MPG.
it's more about what meets a person's need.
MPG really shouldn't be a deciding factor for purchasing a rv. MPG is largely depended on terrain, highway speed, and vehicle.
there is no such thing as good MPG while towing, more like not as bad as it could be and not as good as I'd like it too be...
to the OP, why did you accept a "Smaller" trailer...

We normally get 12 mpg. I did get 14 mpg on a few trips where it was pretty flat and there was no wind and we were driving 55 mph. But, most of the time we are going 60-65 mph and driving up and down hills and in that case we get 11-12 mpg. We chose the smaller trailer as it fits our needs. We try to spend more time outside when camping and find that ours has everything we need and feels like a huge step up when compared to the PUP's we had.

I pull with an under powered Jeep Wrangler 4 dr. I get anywhere from 10 in hard driving going fast, or 14.5 in flat no wind at 58 mph. Normal mixed highway is about 12.5.

Get the Road trip lite app and you can keep really good track of your gas mileage (historical averages and prices). I also recommend the Gas Buddy app to find the best prices for fuel. I have used gas buddy many times to rearrange fuel stops. Sometimes I'll stop with a half tank to be able to bypass a city with unusually high gas prices.

I upgraded to the 184BH from our popup camper. I liked the pup, but I like the TT even more. It is small, but it is the largest thing I can pull with my Jeep. I am not interested in getting a truck.

It's not the size of the equipment... It's how you use it.

We use an 09 Nissan Xterra 4.0L, V-6, 4x4, automatic, almost all towing is done with the "over-drive" option set in the Off position. Is the Xterra underpowered? YES! Did we want new truck payment? NO!
The Xterra gets around 10 to12 mpg when towing our 145RB SLX Baja edition at 55-65 mph.

I have a Dodge Dakota Quad 4.7 and pull a Jayco 17a Ultra I get 10mpg no matter conditions....Went out 3x since we bought it in late summer hoping for slightly better. I asked the same question when we bought ours.

Cheers

The reason I asked about this was after owning 6 different trailers I've noticed that between my 17' Terry and my 32' Hy Line the gas milage differed very slightly. This has led me to believe that it's more about frontal area than length/weight. This is only true (IMHO) at highway speeds. Sooooo the frontal area of my Hy Line was about 60 sq. ft. and my 185rb is about 36 sq. ft. Thats a BIG difference. I guess what I'm sayin is once you poke a hole in the wind the rest of the trailer pretty much follows through.

any thoughts?

I am convinced that improving aerodynamics is the key. I have done a ton of research after realizing the vehicle I was using as a tow vehicle (RAM 1500 4.7 V8) got lousy gas mileage despite being setup with tow package from factory. The trailer (when towed by a conventional pickup) has a huge flat area that catches the wind like a parachute and causes so much drag, the engine needs to work harder to overcome it. The higher the speed, the more drag. The sweet spot for speed is in around the 60 MPH, anything higher, you just burn way more fuel, any slower - might as well stay home. You need to get the flow of air up and over the top of the trailer and if possible reduce the gap between TV and TT. Search "Nosecone" (probably nosecone.com) on the internet, there is a video which clearly demonstrates the benefits of their product - (improving aerodynamics). If there was a way to hinge this nose cone onto my trailer so when parker I could see thru my front window and secure it for driving, I'd install one in a second. Maybe they need to make a "clear" version. They promise you improved fuel economy and better handling. When was the last time you saw a commercial truck/trailer combo without some additions to direct the wind over their trailers? It's not just a theory. Poke that hole as big as you can.
