This is for owners with failed primary lifting mechanisms. It replaces the drive leg connecting to the motor. Lippert or Atwood users will find it compatible. Heavy haulers need this for maximum mechanical stress. DIY enthusiasts appreciate the straightforward drop-in design. Technicians use it for rapid customer repairs.

Verify if the broken part is the lead leg first.

Type	Follow / Idle Leg
Compatibility	Lippert, Venture, Atwood, LCI
Included	Leg and snap pin
Hardware	Brackets not included

What We Found

The Class A Customs follow leg serves as a direct replacement idle leg for fifth-wheel landing gear systems. It comes ready to install with the necessary snap pin included right in the box. This component is engineered for long life and handles the static weight distribution of parked toy haulers.

Compatibility spans most major landing gear sets, including Atwood, Venture, and Lippert models.

Who It’s For

This follow leg targets fifth-wheel toy hauler owners dealing with bent, rusted, or malfunctioning landing gear. It is essential for DIY mechanics looking to restore leveling capability without replacing the entire assembly. Owners of rigs equipped with Lippert, Venture, or Atwood systems will find direct compatibility here.

The part suits anyone hauling heavy ATVs or motorcycles who needs reliable static support when parked. It is not a complete kit, so professional installation help might be needed for inexperienced users. Buyers should verify their current landing gear brand before ordering to guarantee a proper mechanical fit.

Keeping a spare follow leg in the garage prevents extended downtime during unexpected campground failures.

What to Look For Before Buying

Choosing accessories for a fifth wheel under forty feet demands attention to sizing. Undersized covers leave sections exposed. Oversized options catch wind and tear. Landing gear replacements must match specific brands. Prioritizing verified waterproof ratings ensures long-term protection.

Check Match Cover Dimensions Precisely to Your Trailer Length

Always measure from the front bumper to the rear edge. A cover for thirty-seven feet will billow on a thirty-two-foot rig. Excess fabric catches wind and degrades material. Stretching a small cover stresses seams to failure. Use manufacturer charts rather than advertised maximums.

Value Prioritize Multi-Layer Fabrics With Verified UV Ratings

Look for covers with seven to nine layers on the roof. The roof takes the brunt of sun and debris. Check for quantified UV-blocking percentages. Products listing specific blockage rates offer verifiable protection. Higher layer counts generally mean longer lifespans in harsh climates.

Rating Evaluate Strap Systems and Corner Reinforcements

A cover is only as effective as its holding system. Seek designs with eight or more undercarriage straps. Elasticized hems prevent lifting in high winds. Inspect images for reinforced patches at all corners. Sponge-lined gutter covers prevent sharp edges from slicing fabric.

Verify Confirm Landing Gear Compatibility Before Ordering Parts

Replacing a leg requires knowing if it is lead or follow. The lead leg connects to the drive mechanism. The follow leg provides passive support. Cross-reference part numbers with brands like Lippert. Most legs exclude mounting brackets, so reuse existing hardware.

Frequently Asked Questions

How do I measure my fifth-wheel toy hauler for a cover?

Measure the overall exterior length from front to rear. Do not measure just the interior living space. Compare this exact measurement against manufacturer size ranges. Choosing a range where your trailer sits in the middle ensures the best fit.

Are nine-layer RV covers really better than standard ones?

Nine-layer covers provide better protection against UV degradation and hail. The multiple layers create a dense barrier against moisture. Standard covers often use fewer layers and wear out faster. Investing in thicker fabric preserves the trailer’s resale value.

Can I access my toy hauler garage without removing the whole cover?

Yes, certain premium covers feature dedicated rear zipper panels. These zippers allow you to roll up the back section for loading. Standard covers usually only offer side passenger doors. Look for models explicitly mentioning rear access or toy hauler compatibility.

What is the difference between a lead leg and a follow leg?

The lead leg houses the gearbox and connects to the motor. It bears the mechanical load for raising the trailer. The follow leg simply moves in tandem for balanced support. Replacing the wrong leg results in a non-functional system.

Do I need gutter covers for my RV cover installation?

Gutter covers are essential because sharp spouts puncture fabrics. Quality kits include sponge-lined guards for these edges. Without them, wind movement causes rubbing and tearing. Always install provided gutter covers before draping the main fabric.

🎯 Final Verdict

The RVMasking Travel Trailer RV Cover stands out for protecting a fifth wheel under forty feet. Its rear zipper panel solves the biggest frustration for owners. You can load ATVs without dismantling the cover. The eight-corner reinforcement provides unmatched durability. For broader UV protection, the DenForste cover offers lab-tested shielding.
