Coil Springs vs. Leaf Springs (w/ towing)
 

I am very close to purchasing an Avalanche, but I have a question regardng the rear coil springs in relation to towing. I have a 6,500 pound boat that I will be trailering four times a year for a fairly short distance. I am concerned that the coil springs may not hold up over the long run (years) compared to leaf springs. Any comments?

PS
Regarding comments i have seen in relation to the Avalanche vs. a "real truck".... I have had my Dodge RAM 4x4 1500 for ten years and am looking for something different yet able to; tow a good size cabin cruiser, the ocassional need to haul an ATV, load a 18' kayak on top, occassional use of a truck box..... I consider myself a country boy originally from the Catskill Mountain area and now living in the Adirondacks, but i have really taken a liking to the new Avalanch. Yes it is very unusual looking, but seems to have a nice combination of comfort, available seating, and trucking abilities. If I trailered more often and used the box constantly, etc. - yes i also would go with the standard truck, but you don't necesarily have to be a "suberbinite" to like the things the new Avalanch has to offer.

wondering the same thing
 

My Avalanche squatted quite a bit just hooking my 18' Bass Boat on the back as compared to my Silverado, so i was wondering if they make some kind of spacer to stiffen up the coil springs. I have since sold my boat but was just curious. I don't remember my buddies Av squatting as much when he hauled his 21' Bass Boat, but his trailer was a tandem axle.

If the tongue weight of the trailer is within max weight allowed on the Av you will be alright. There is self leveling air rear shock option for the Av. I would think that with a 6500lb boat you should use a leveling hitch.

Avoid those trucks and i say that as a chevy guy for life.check the reviews.
