Am wondering how a class C behaves in the wind considering the front over hang. With all that overhand above the cab, is there some effect in front head winds that wouldn't be experienced ina Class A?

I have not heard of any wind effect that is generic with Class C body styles. Neither A's nor C's are exactly what you could call aerodynamic - both are big plows just bulling their way through the air. Wind resistence on the front affects gas mileage a lot, but probably doesn't alter handling much.

Most RV wind effects come from the side, which acts like a big sail. Steady side winds tend to create a push that requires the steering wheel to be turned a bit to compensate. The rig may look like it is going down the road at an angle, but it is OK. Can be tiring on the driver, though.
The biggest wind problem is gusts, including those caused by passing vehicles. When the wind pushes on the rear quarter, the rear end moves sideways on the suspension and causes the front end to move the opposite way, requiring steering correction. When the gust ceases (as when a truck moves past you), the front end quickly snaps back straight and you need to "uncorrect" quickly. Both A's and C's do this, but the amount depends on the rear overhang, susension quality and weight distribution.

Several yrs. ago, I decided to downgrade from class A to C. Bought 24ft. Shasta (1997) Ford chassis. Big mistake! Wind affects both MH's equally, but what bothered me was the way the C "rock and rolled" down the hywy! I find it much easier to drive my 37ft. class A than the C. Just my experience.

As Gary has mentioned, wind-effects are usually associated with rear over-hang.

A general rule-of-thumb for RVs, is that the wheel-base should exceed 53% of the total vehicle length. The longer the wheelbase, the less susceptible the rig will be to side-winds, with side *gusts* being even worse.

Weight distribution is also a primary onsideration; like . . . there are a whole lot of really badly-designed out there, with some 800 lbs of water-tank mounted *behind* the rear wheels, to the point that your front wheels are almost air-born. Duh! A bad scenario, whether with Class C or A; and Winnebago seems to be one of the most prominent offenders in this area.

Tire profile is also an important factor. Most recent RVs now utilize a 19" wheel rather than a 16" one. Rigs with 16" wheels tended to be a lot less stabile on the road. While the outside circumference of the tires remains the same, the lower-profile 19" tires tends to be significantly more stable. And in a world where nothing ever comes for free, the downside is that low-profile 19" tires tend to ride a tad harder.

Good input. Thanks. I had a class A, I had 2 TTs. Am primarily looking at a 5ver but the Jayco Seneca HA caught my eye. Mostly because of the Duramax up front. So it seems to be quite a bit differnt that the "usualy" class-c on a van chassis. Wheel base to length is 58% so that's not bad. Still tho, I think I'll end up with the 5ver. Mostly I just didn't know if the front overhand caused any more than the usual wind buffeting. So far - not from what I read. I'll keep monitoring for more input.
