The rear suspension on my truck is so stiff, that I've got to change it. I'm currently running the Downey AAL and Ranch RS99144 shocks. Some people have mentioned I should try changing the shocks, but I just don't buy it. I thought the weight of a camper shell would help some, but it really hasn't. Therefore, I'm opting for 2 different setups. The one setup is the Deaver 3 leaf, 1" lift shackles, and some 5100s. The other setup is a set of Alcans and 5100s. For those that have gone from the 3leaf to the full leaf pack, or that have ridden in both, is there a considerable different in the ride for $200+? I've searched posts and have read how much better each one rides when compared to a single AAL, which is obvious, but I couldn't find any info comparing the two. I'm curious to know if the extra money for the Alcans is justifiable.
