I don't think there is any inherent price difference between pusher and puller. However, a puller chassis is often also an entry level chassis and there may be other cost saving factors that create a price differential but also contribute to more noise, harsher ride, etc. Some previous puller models have had 4 or 5 speed trannys, leaf springs instead of air bags, hydraulic brakes instead of air, etc.
With a pusher you lose substantial rear storage space, inside and out, but gain space back with the cavernous "pass through" mid storage made possible by the lack of a driveshaft running down the center. With a pusher the engine room encroaches on the rear bedroom, typically costing under-bed storage and/or makng a raised platform in the rear. With a puller, the engine room is under the driving area and typically creates a raised area there, often called a doghouse if it is a center "hump" but in todays pullers the raised front is likely to be pretty much flat. All this is generalities - individual models will vary widely but there are always tradeoffs.
Fan noise is a biggie in a puller (gas or diesel) - you really hear the cooling fans cut in when hill climbing or at 95+ temperatures. You are also aware of downshifts. Tire noise should be about the same in both, but air suspensions seem to transmit less noise than springs.
