Description

Keystone Cougar Half-Ton fifth wheel 26RES highlights:

L-Shaped Sectional Sofa
18' Power Awning
Front Private Bedroom
Ceiling Fan

Comfort is just a step away in this fifth wheel with a large slide out. Here, you'll find the hidden pantry behind the pivoting entertainment door plus your kitchen appliances. The stainless steel sink will let you easily clean up, and the pivot dinette with two extra folding chairs provides versatile space to dine or work. Your crew can get comfortable on the L-shaped sofa after dinner, or head outdoors under the 18' power awning. A full bath lets you clean up after a day at the lake, and the front private bedroom with a king bed gives you your own space at night. There are also dual wardrobes and nightstands plus a wardrobe with washer and dryer prep for the option to go full-time!

The Keystone Cougar Half-Ton fifth wheel and travel trailers are known as one of America's favorites for a reason! Some of those reasons are the exclusive features that come from Keystone, like the Winegard Air 360+ omni-directional rooftop antenna, the in-floor heating ducts, and the HyperCore composite wall construction with Vixen Fibrogloss high-gloss finish. The Cougar Half-Ton has a Climate Guard protection package with heat-deflecting white sidewalls, two roof attic vents, PEX plumbing and more to enjoy four season camping. Inside, you'll love the dimmable lighting, night roller shades throughout, shower skylight, and bedside USB outlets to keep your electronics charged.

I bought a used rv from here. It was supposed to have been gone through and have no problems. Well I picked it up and drove 9 hours with it and the hot water heater wouldn’t work and the toilet leaked.

Priced new slide awning at all the RV dealerships in Tyler and RV Station was less than the others and RV Station price included installation and the others was only the awning.
