Tiffin Allegro Red 33AA 360HP vs 340HP

Hello, I am in the market to purchase a Tiffin Allegro Red 33AA. I'll be upgrading from a Bounder 33C. I have looked at several new and late model coaches. I would like the opinions of current owners on whether the newer engine/transmission package (360HP) with the Allison 3000 transmission is something that is really worth purchasing a 2016 or 2017 for over a less expensive pre owned 2015 with the 340HP.

I had thought I would like to have the 360HP version as I'm aware of the increase in torque from 660 to 800lb and towing capacity from 5000 to 10000lbs. I plan to use the RV on trips from FL into the east coast mountains of NC and VA with no Toad most of the time. I also have hopes of going West into the Rockies at some point as well. I have only been able to test drive coaches in flat florida, and I only notice a slight difference in performance as far as acceleration. But, I wonder about how they will differ in the mountains? But this could change in the future. Thanks in advance for your opinions.

Michael

Welcome to iRV2.

JMHO: Without knowing if the 340 HP RV has the 2500 series Allison ( max HP for that trans). I'd say go for the higher HP/Torque/Tow capacity. The lower tow rating in particular , restricts any choices in toads for your longer trips.
The higher ratings will probably help resale $$$ too.

We have the 340HP, run up and down the east coast all the time, have been out west and going out again this summer for 3 months and pull a toad. The 340 is very driveable, and has been a great coach.

If I was buying a used coach, I would have no problem buying a 340 again. If I were buying new, I'd probably pay extra for the 360. It's the same engine as the the 340 with a different ECM tune, it's the transmission where the main physical difference is (3000 vs 2500). I don't have any plans or need to tow more than 5K, so there is really nothing about the 360 combo that I NEED. However you can always use more HP, no matter what you have (motorcycles, cars, RV's, boats)


I'll enclose a copy of my VMSPC, we typically drive on cruise control at 60 - 65 based on traffic, and the % of engine load runs between 10-40% on normal interstate runs. I've gotten 10.5 mpg over the life of our coach. I do much better at highway speeds than local urban travel.

Feel free to PM me if you have any specific questions.

I agree with DaveB. We have the 340hp with the 2500 Allison and it is very driveable. We are almost always towing a 3800lb Jeep and have done mountains and plains with no problems. It doesn't break any speed records going up grades, but it is comfortable to drive. We bought ours at the end of the model year and didn't have a choice. If I was ordering new, I would go with the 360/3000 combination just for the extra torque and towing.

I to am on the fence re the 340 vs 360 motor in a 33aa. In 2016 the 360/3000 was a option and 2017 the standard MT combo.
I prefer to buy used to save money either 2016 with the 360/3000 motor or a 2014 340/2500. The shopping continues.
Great feedback on the 2 motors .

Hello Michael...We have the 360/ 3000 combo in our 2016 Allegro Red 38QRA and love it. We upgraded from a 2016 Open Road 32SA with the V10 because we needed more torque and tow capacity. Towing flatis no problem , when were going up grade we drop down to about 45-48 mph. Slower than some but fater than others. Good luck in your hunt.

We opted for the 360 motor and the 3000 Allison tranny. Am very happy with it. It tows my jeep on a tow dolly and gets 8.5 mpg at 60 mph.

Hard to believe you're taking that much of a mpg hit. I would think your mileage will improve.

That is an average mpg. We did a lot of mountain and hill driving. This also included much of our driving on the back roads with little driving on interstate highways.

Curious why you dolly the jeep rather than flat tow?

Jeep is a front wheel drive Cherokee Latitude. We could not find one that could be flat towed.

Same coach in 340hp version gets 10.5

A 2 mpg difference is much more than what I would have guesstimated, since it's the same weight coach, same aerodynamics, same physical engine with a different tune.
