Default trailer or TV

this is probably just a hypothetical question, since we probably won't do anything about it.

we have a 2015 grand caravan, which we paid much more for than the fun finder.
I am beginning to feel some concern about the stress of towing a trailer with the front drag of the fun finder. as pointed out in the gas milage thread, it isn't the weight, but the frontal area that is hard for the TV to pull. so our trailer is light enough, but exceeds the "frontal area restriction" by 19 sq. ft. However, I have discovered a very nebulous area surrounding tow ratings of my van. dodge told me my van, based on vin, has a heavy duty engine cooler and heavy duty transmission cooler. It does not over heat, but I worry still, because there is still the touring suspension as opposed to towing suspension. I don't know what else would make a van equipped to tow; heavier wheel bearings? brakes?

the crazy thing, is that the van does just fine. at least I don't have another vehicle to compare it with, never having towed a trailer before. It slows down going up hill, of course, and shifting down manually to keep it in a good gear works. One mechanic said not to tow with it, two others said it's fine. all said we couldn't go wrong with an extra tranny cooler.

I know that towing with a grand caravan has been discussed, and sorry to bring it up again.

I'm wondering now if an R-pod type trailer would be easier to tow because of the sloped front and rear. just theoretically, since I think they may be too heavy for my van to tow. (even though they say "mini-van towable")

I wonder if a fiberglass casita type would be easier. again, theoretically, since they are so expensive and somewhat claustrophobic.

I suppose we will continue to use the GC, put on some kind of rear suspension support and a tranny cooler. then we are probably close to the tow package that boasts 3600#. but still over the frontal area restriction.

I think the brakes on the van may be an issue -- I had a Grand Caravan 20 years ago and warped the rotors by braking too hard. (Not while towing.) I have since learned my lesson, and maybe the brake design has improved since then.

Maybe R-Pods and Casitas are more aerodynamic, but I haven't heard that they get much better mileage, so that would cast some doubt on that theory. And the sloping front wall cuts off a lot of living space. The only really aerodynamic trailer is a pop-up, which has its own substantial drawbacks.

we tried a pop up, briefly, not good for our needs. the r pod, hummingbird, rov, winniedrop campers are only livable with a side out, and that makes them heavy. and they are expensive. I really do prefer the little t139 that we have. I may be looking for an opportunity to trade in the van....
I think much has been improved on the grand caravan, at leas I hope so. I know transmissions used to be a real weak point.

a dodge technical advisor on their website finally sent me a link to some good info. our van (according to vin#) is rated for 3600# so I feel better about that. we still are over the front area restriction, but he also directed me to a very detailed owner's manual on line. I just found the info about towing that makes me feel better. you are supposed to use the ERS (electronic range select) when towing. that is just the feature that allows you to select the gear that you think best. I was worried that manually selecting the gear meant the tranny was over worked. knowing that it is the proper way to drive it reassures me.

Yes -- if you don't use ERS, you could be forcing the transmission to "hunt," where it shifts up and down continually. Hunting supposedly is hard on the components -- not sure why, but that is what they say.

sort of off topic, but not really. those of you with smooth sided fun finders, wonder what you thin of these? airtab.com
I would order them, but they can't be installed on a trailer with corrugated metal sides.

Airtabs do work -- on big rigs, they are proven to add about one-half mile per gallon. But big trucks drive many more miles per year than we do -- so the cost of the airtabs is "amortized" over lots of miles. They are probably not cost-effective for travel trailers.

I'm kind of excited! we did buy a new to us tow vehicle. 05 toyota 4 runner. we took it for a test tow, and it is going to be a lot better for towing than the van. to start with the tow limit is 5000. the suspension is much stiffer and it is rear wheel drive. I've been spending a little time looking at a toyota 4 runner forum, and I'm amazed at what people tow with them. our little trailer will be easy for it.

After a very frustrating, but probably wise delay, we finally have our 4 runner. brake controller, plug and go, hitch etc. installed. so easy! It tows like a dream.

the dealership decided the vehicle needed work before it was sold...sort of after we bought it. I'm glad, it is like new, but I was really second guessing the decision to buy it. I suppose a used vehicle can always have "hidden" problems, and this one may still. but when I told them I would buy it after they addressed the road noise from "big tires", the sales man was told they were still waiting a bearing for the pinion gear in the differential. just a miscommunication, but un nerving just the same.

now it is smooth and quiet. It feels like a new vehicle.

camping on Monday!!
