FRUNO Oxford Fabric 5th Wheel RV Cover Fits 37ft-41ft - Waterproof

In this review the FRUNO 5th Wheel RV cover is evaluated for owners of toy hauler and fifth wheel trailers measuring 37 ft to 41 ft. The bottom line: this cover is best for RV owners who need a robust, weatherproof solution that stands up to winter snow and sun exposure. The standout reason to buy is the combination of heavy-duty 300D Oxford on top with 150D sides and a dense PU coating, which together provide reliable waterproofing and UV protection while remaining usable year round.

Key Features

• Premium material: Heavy-duty 300D Oxford fabric on the top and 150D on the sides gives a durable, tightly woven shell that keeps water and air out.
• Waterproof and temperature resistant: The dense PU coating and weave deliver full waterproof protection and tolerate temperatures from -4F (-20C) to 120F (49C).
• Wind secure fit: Side straps fixed in the middle, elastic hem and adjustable front and rear straps create a closer fit to reduce flapping and tearing in heavy wind.
• Enterable panels: Four rollable panels with zippers and internal velcro let you access the trailer without removing the whole cover, useful for checks or short tasks.
• Complete kit: The set includes four tire covers, two lashing straps, six gutter spout covers, repair patches and a storage bag for a full-season solution.

Who It's For

This cover is aimed at fifth wheel and toy hauler owners who need a heavy-duty, all-weather protective cover for units roughly 37 ft to 41 ft long. It suits owners who store trailers outdoors in winter or sun-exposed climates and want UV inhibitors and waterproofing to extend exterior life.

Those who should look elsewhere are owners of shorter or longer trailers outside the 37 ft to 41 ft range, or buyers who prefer lightweight, breathable covers for daily short-term use; this cover prioritizes waterproofing and durability over maximum breathability.

Pros & Cons

Pros

• High quality fabric and PU coating deliver dependable waterproof protection and strong UV resistance.
• Secure attachment system with elastic hem, mid-side straps and lashing straps reduces movement in wind.
• Enterable roll-up panels make routine access and inspections straightforward without full removal.
• Complete accessories package includes tire covers, gutter spout covers and repair patches for practical long-term use.

Cons

• The dense, air-impermeable fabric favors waterproofing over breathability, which may trap moisture if not monitored.
• Proper fit requires accurate measurement including bumper, ladder and spare tire, so shopping mistakes can occur if measured incorrectly.
