Freightliner vs Powerglide chassis

I am in the process of purchasing a Tiffin Rv and I am looking at both the AH and IH and see that they both have different chassis. Will be traveling around the country. What is the difference between the two and which would you purchase if all other things as floor plan would be equal. Why and why not? Is there anything that is a must to have and something that is not needed when putting together options? I know this last question is personal but ideas are always welcome! CAN'T WAIT to order and hit the road. Parttime to start than fulltime down the road.

Welcome to the forums, searching will give you some perspective as this is a topic from time to time.

One of those choices has a continent wide network of service facilities and the backing of a global heavy vehicle manufacturer.

Been through all the continental states and provinces. Rinse and repeat. Present coach 2018 VTDP 3407.

Freightliner makes a fine chassis but the chassis that Tiffin specifies is not equivalent to the Powerglide. If Tiffin used more closely matched Freightliner than the issue is over, but between the two that Tiffin puts under the Phaeton the Powerglide is superior. That said, floorplan is what you live with everyday and if the floorplan doesn't work for you the chassis really doesn't matter.

Well, I just purchased a 2019 40 IH with the 450PH Chassis. Still waiting for some things to be finished up before taking delivery next week. While shopping I also drove a 2016 QBH with the 380 and Freightliner chassis for comparison. Putting aside the different power output, the ride quality of both was comparable but the turning radius of the Powerglide was superior. I drove into a dead-end business park parking lot by mistake and was able to turn the coach almost within itís own radius! Between that and the more powerful engine made it an easy choice for me.

Your options really are up to your preferences. For me a dishwasher and heated floors topped my list. I also preferred an all electric coach, in motion tv dish, washer & dryer... When shopping I saw a lot of the same options on the lots. Of course if you plan on special ordering your coach, !

We have been very pleased with the powerglide chassis. I agree with wjohnson913 that the floorplan is more important.

For us the Aquahot is a must have, one of our favorite features.

Because floor plan is so important we are staying put in our RED 37PA. Once Tiffin puts the Phaeton 40AH on the powerglide we will jump on it. We are not willing to give up the floorplan.

We have had two comparable size Tiffin coaches, one on a Freightliner and the current one on a Power Glide. I think the ride is more stable and smoother on the Power Glide with the IFS. To me it has been much more comfortable to drive in the wind that the FL. The turning radius has already been mentioned and that is a definite plus. The other benefit is the added 7" of height in the storage bays, but the down side of that is the coach is 5" taller overall.

I too have owned both chassis and there is no question in my mind the ride, handling, and maneuverability of the Powerglide surpasses the Freightliner. I do agree the floorplan is important, but I have to drive the thing and I feel comfortable and safe going down the road all the time. Can't say that about our last rig.

When inquiring at the factory of the differences between PG and FL chassis on our bus. Was told the engine is 4 inches lower in frame than the FL chassis. Which is a plus for handling, but ground clearance is lower as well. At ride height there is 8 inches of clearance on crossover exhaust pipe. Which is lower then oil pan. I don't dare run over a "tire gator"...ever.
