I have the Winegard MV3500A, and recently it exhibited similar symptoms. It was flaky, and deteriorating. Bad LNB. I had a spare dish, so I scarfed the LNB from it & installed it on the roof MV3500A. Problem solved.
Thudman </div></BLOCKQUOTE>Huh?? But how much does the LNB weigh
Back to the question...
My weight distribution (you can look at my previous posts where I have posted my four-corner weights) isn't too bad but the problem on the pre-2006 Vectra/Horizons is the front axle capacity is 12,000 pounds and you can quickly take the front axle to the max limit. With an upgrade to Load Range "H" tires on the front, you are good for several hundred more pounds (the only difference from pre-2006 to post-2006 Vectra/Horizon front axles is the steering box.)
The Winnie engineers have done a really good job (at least in my coach) of spreading the load out among all wheel positions. In fact, I hold Winnie engineering in very high regard based on my 30,000 mile experience with my coach.
