Like already said, floorplan and features is what you need to look at, and what should be the main determining factor here.
We looked at both of the models being compared here, the Allegro 35QBA and Winnebago 35B (as well as a few others). We really did not like the Allegro 35QBA floorplan as much, for 2 reasons:
1. Did not like that kitchen slideout on curb side - When that slide is out, it really cuts into your space outside, under the awning. Never have liked any slideout that cuts into your space under the awning.
2. Absolutely hated how the recliner/chair is behind the main door, instead of in front of it on many other models.
For those reasons and several others, we ended up with the Georgetown 351DS, which has a very similar floorplan to the Winnebago 35B. Only reason we didnt go with the Winnebago: Only dealer around here that carried it was not very willing to deal, whereas Georgetown dealer made us a really, really good offer we couldn't turn down.
One other thing I'd like to mention:
At 35 foot I would think the 24,000 lb chassis would be better, sounds like the 22,000lb would be max weight on a 35 foot motorhome...
..Not true at all. Our 36' Georgetown 351DS (similar floorplan to the Winnebago 35B mentioned here) sits on the 20,500 chassis with 19.5 rims. It is not anywhere NEAR 'max weight'. MH weighs around 16,800 empty, leaving plenty of payload capacity (close to 4,000 lbs). And, yes, I have verified this with a trip to the CAT scales. And, yes, it rides very well, we are very happy with it.
I prefer the 20,500 chassis and 19.5 rims. Tires are a good bit less expensive to replace, and easier to put on/off.
But, like already said, of the two models mentioned, handling and road manners will be very close to the same. The choice comes down to which floorplan, features you like best.
