Jayco's Jay Flight 26BH/27BH and Jay Flight Swift 264BH Triplets are very popular

My 5.0L 2012 F150 pulls it easily. Just get good sway control as it's 29' long. The 3/4 ton is a good idea to get extra payload but isn't it wasted on an Avalanche that has such a small bed, length and width?

This trailer is definitely 1/2 ton towable as it's pretty light not having a slide. One of the big pluses of it, tons of room, stick and tin, tall ceiling, yet it's still light!
