We have a new Trail Runner 27RKS and we were wondering how your slide operates compared to ours. Ours seems like it operates very slow. Almost stopping when sliding it out or in. Like the motor doesn't have enough power. Thinking that our battery might be low on juice, I hooked up our Duracell Power Pack that was freshly charged to compare. The slide operation was the same. Is it normal for these slides to operate so slowly? It was so bad that I was getting nervous thinking it was going to quit working with the slide partly deployed.
