Double-over-double bunks are the headline here, and at just under 22 feet and around 3,900 lbs, this is a genuinely easy trailer to tow for families who don't want to step up to a larger rig. Forest River throws in some legitimately useful upgrades as standard. The 13,500 BTU roof-mounted AC is a meaningful step up from the side-mount 8,000 BTU unit, and the refrigerator runs 36% larger than other LE models in the lineup. The whole floor is luxury vinyl (no carpet anywhere), and the sofa seating, residential high-rise kitchen faucet, and backup camera prep round out a surprisingly practical interior for the price point.
