Yup there is the original price difference between the V6 and V8 to consider but don't forget to add the increase in insurance cost per year as well for the V8 over the V6 - here your rates go up with value of the vehicle.

I know we hear a lot about the transmission issues etc when pulling with smaller tugs but yet we don't hear of to many people (actually trying to recall anyone) here indicating they have destroyed their transmission pulling a trailer within the tow specifications of the tug regardless of its engine size. At least not in recent times... perhaps they just don't want to admit it happened or with newer vehicles it isn't a frequent an event as it is frequently discussed. I pulled a 16' with a 4 cylinder for thousands of miles with no transmission problems over lots of big grade hills -11% pretty common as well as some higher grades - had the transmission fluid changed out and checked... not a sign of a problem.

Agree though that having more power for the hills is better thus why I have upgraded to a V6. ;-)

I think I'm more convinced the V8 is for me. We are buying the new Jeep to primarily perform as a tow vehicle. We have a Honda Accord for everyday driving. We are both getting to retirement age and this is suppose to be fun. I would use the old Cherokee as a tug, but it's old and it sounds like it is working very hard simply driving the flatland. MPG on the new vehicle will likely be better anyway with the V8 than what I "enjoy" now. The old Jeep seems to get 13-14 MPG around town. And besides, I like to go fast!

We intend to be out West, not in Nebraska for most of our travels. I am an avid fly fisherman and we want to get into just about anywhere, even if there aren't always roads.

That's just about it. First trip...to Moab Utah to get the new Jeep blessed in the shadow of delicate arch. It seems to be the place where Jeeps are most at home. Thanks for your opinions. I appreciate all the comments.

Tim, you make a good point, the newer vehicles with larger engines are getting better with MPG each year. I have a a 3 year old V6 truck that is getting the same milage around town as my 07 4 cyl. Outback & about the same mpg on the highway, So the old mpg argument doesnt hold as much weight in arguing against going with a bit more power.

Throwing aside possible insurance/initial vehicle costs, I'll take the extra hp any time, unless you will almost never be towing, and will be putting lots of regular miles on it.

I pulled a 5,000+ pound trailer to the races and back on a 50 mile round trip for several years with an 135 hp '89 nissan. It worked, it was safe, but it wasn't fun, and it wasn't relaxing puttering up the hills in third gear.

Setting the cruise at 75 in the 350hp truck with the 3500 pound scamp and only having the transmission kick down on one hill (sometimes not even that one, depending on wind) between wichita and Minneapolis? Priceless, relaxing, and fun.

For me, the subaru is to get good mileage, the truck is to easily pull/haul whatever comes it's way, regardless of mileage.

Also, the subaru goes from 30-31mpg down to 23 mpg pulling a 500 pound 4x8 flatbed trailer. The truck goes from 17 down to 12.5 pulling a 3500 pound fifth wheel. I'm not saying a v8 will get better mileage than a v6 towing, but it will likely drop less from the initial mpg.

Right, I really think the V8 towing would be the same or maybe 1 mpg less, vs the V6 in the same Jeep. Not much difference. But the longevity of the stronger engine and beefier transmission should be greater, which benefits the person who likes to hold a vehicle for many years.

Are you getting the Off Road II package? I'm thinking the Off Road I will be enough for me... especially after I heard that the shocks for the QuadraLift air suspension are $1100 apiece at the dealer.

I am looking at the Limited version with leather, normal suspension, the 8HP70 tranny, 5.7L HEMI, Uconnect 8.4 with NAV, 20" wheels, Trailer Tow IV and Off Road I.

I don't really want the fancy suspension. I want something that tows like a pickup, has enough creature comfort and navigation for long trips (without a windshield full of electronics like I have now) and has a four wheel drive system that will help me keep from getting stuck. I thought the 20" wheels would help with clearance and give me better height for the hi-lift axle on the Casita.

I like the idea of all the skid plates with either off road package. After having a vehicle with none at all, I see what they will prevent. I think they'll also keep flying salt off the bottom of everything under there so the vehicle will last longer before any serious corrosion shows up to end the useful life of the vehicle. I always intend to keep a vehicle A LONG TIME. I'm much better at buying than I am at selling vehicles.

Did you see the new Jeep GC is all galvanized and aluminum. No plain old steel to rust! I've spent a lot of time under my '96 Cherokee sand blasting the bottom to coat it with POR15 and Rust Bullet. That's how I've been fighting the Nebraska road salt to get nearly 300,000 miles out of it.

My achin' head...do you folks have any idea how much you sound like all the guys over in The Big Boys Towing Forums like RV.net? "Bigger is better", no matter how you cut it.

Can't wait for the Fordvs.Dodgevs.Chevy controversy to start ragin' over here in the erstwhile "we tow small" capital of the Virtual RVers World!

Ask the dealer what the skid plates are made of and how they are attached.
My buddy discovered the "skid plate" on his Hyundai was made of plastic when he broke it on a snow bank...

Mileage aside, pretty much. Nobody said it was necessary, opinions were asked and given.

Mike you may be correct on the towing MPG between the two engines but I'm not so sure on your longevity assumptions. The 3.6L Pentastar V6 is top rated engine and at 285 HP it has a higher HP rating than the previous V8's.

If all I was going to be doing with the vehicle is towing, and towing hard, then the V8 would be my choice. Since that is not the case, the Pentastar V6 was the better option for us and with the way I actually use the vehicle I would expect it to outlive the V8 with better mileage throughout it's life. Time will tell.

By the way, I was making the same decision as you a year ago and decided on the 2011 Dodge Durango Crew with the Pentastar V6. My nephew is a mechanic and he highly recommended this engine. We've been very happy with it so far. We drove and liked the Jeep as well but wanted more cargo area.

Good luck on your decision.

Randy

Just make sure you take a look at the payload rating on the model with the skid plates vs the ones without.... you *may* find there is a drop in payload rating on the one with skid plates which depending on the number of passengers you plan to carry, cargo and trailer tongue weight it may or may not be an issue for you.

Randy P.-

How big and how much does your Jayco weigh? I am assuming that's what you are pulling with your Durango.

If the Jayco is at least the weight of the Casita 17, you are the kind of person I was expecting to hear from. You have the V6. Is that exactly the same engine?

I just got my used Casita last fall and the only people I have seen around here with a trailer like mine are pulling them with big pickups. Maybe you don't need that, but that's been what I have seen. I don't think a medium sized SUV is out of line for this trailer. Besides, I like the vehicle. I think they use the same 5.7L HEMI in the Ram 1500 pickups.

Tim,

I've never actually pulled the Jayco with the Durango as I just got it last November. We purchased it in order to tow a 17' Casita Spirit Deluxe that we will be picking up next month.

Our Durango has the factory tow package and is rated for 6400 pounds so I'm confident it will be up to the task. This has been the experience of other owners who post on the Dodge forums as well.

Now if I were planning on doing a lot of towing in the mountains, or heavier loads, I would opt for the V8 as I believe the additional torque would be helpful but for our Casita and our intended use, I think it will work well.

The Dodge and Jeep have a similar lineage so I assume the engines are the same or nearly so. I was surprised at the performance they're getting out of the newer generation V6s and just wanted to provide that perspective for your consideration.

Of course there are other reasons to get the V8 so if those suit your circumstances better, by all means go with what you think best and enjoy!

Tim, check the tire sizes that come with the 18s and the 20s. I am not positive but I am pretty sure I read that the overall circumferences are pretty close... meaning that the 20s are lower profile tires than the 18s. This would mean that the 20s (standard ones at least) would not give extra clearance.

The off road packages substitute 18s for the 20s. The reasoning seems to be that the higher profile 18s have more sidewall to flex and can better handle the off road stuff without being punctured. They say it's good to air down a little for off road, too, and low profile tires can't take that. I guess you could always replace them with larger circumference tires at some point, though, and gain some clearance. 8.5" with skid plates is already pretty good.

(edit): I found it.
265/50R20 tires = 95.6" circumference
265/60R18 tires = 95.8" circumference
