RV Designer G21 Gas Prop Door Support
Features: 20 inch extended length, 10 lb force. Commonly used on RV entry doors. Replaces the gas prop by matching length and force as closely as possible. One gas prop per package.
Best for: Buyers with standard RV entry doors that require a light to moderate lift and a typical 20″ stroke. This option is a straightforward swap for those with the G21 or similar gas props.
Caution: Ensure the exact length and force match of your original part to avoid improper operation or fit. This model is a basic replacement with modest lift, so very heavy lids may require stronger options.
Euplokeer 20in 20lb Gas Strut Set
Features: Direct replacement for RV entry storage doors, RV compartments, beds, and more. Includes two gas springs with mounting brackets. Interchangeable with several listed part numbers; compatibility should be confirmed by cylinder part numbers.
Best for: DIYers needing a versatile, two-pack solution for multiple RV doors or compartments. The two-piece set is helpful when you replace both sides or want a spare.
Caution: Verify that your original cylinder numbers align with the listed compatibility. The long list of compatible codes can be confusing; mis-matching could affect fit or operation.
PAMAGOO 23 Inch Heavy Duty Doors Lift
Features: 23 inch extended length; 100 lb load capacity; designed for heavy lids like RV storage compartments and bed lifts. Includes mounting brackets and hardware (per listing).
Best for: Applications requiring substantial lifting force, such as heavy RV compartments or bed lifts. Choose this if standard 20″ slats are insufficient or your door carries heavier loads.
Limitation: This is a longer actuator with higher force. It may be overkill for small compartments or light doors, and fitment should be checked against door height and hinge spacing.
GEAIN 20 Inch Door Gas Strut for G22
Features: 20 inch, 20 lb load capacity, replacement for RV Designer G22 doors. Suitable for camper doors, trailer lids, and toolboxes. Provides sufficient lift to hold open the door while not making it hard to close.
Best for: Replacing a door prop on G22-class RV doors or similar sizes where a balanced lift is needed. This option aligns well with doors needing a precise, moderate hold-open force.
Caution: Ensure compatibility with your exact door model and hinge configuration. Different RV door designs may require a different stroke length or mounting arrangement.
Buying Guide
- Length and lift: Measure the extended length and confirm the closed length of your current gas strut. Typical RV doors use around 20 inches, but some lids need longer travel (23″ in PAMAGOO’s set).
- Load capacity: Choose a force that matches your door weight and lid. Lighter doors tolerate 10–20 lb; heavier compartments may require 23″ with 60–100 lb equivalents.
- Mounting compatibility: Check mounting brackets and screw patterns. Some sets include brackets; others require compatible hardware listed in the product features.
- One vs. two-pack: If both sides have props or you want backup, a two-pack of gas struts can be more cost-efficient and ensure consistent lifting.
- Replacement compatibility: Some products specify compatibility with RV door models (like G21 or G22). Confirm your door model and part numbers before purchasing.
- Installation effort: Most gas struts are straightforward to install with basic tools. If your door uses unusual mounting points, you may need extra brackets or adapters.
- Common limitations: Higher load models (like PAMAGOO’s 100 lb) can be overkill for small doors and may require more robust mounting to avoid door misalignment.
Frequently Asked Questions
- How do I know my RV door needs a gas shock kit? If your door no longer stays open, closes too quickly, or feels weak, a gas shock kit is a common restoration option.
- What length should I choose? Match the extended length (typically 20 or 23 inches) to your current door prop or the door’s clear opening height.
- Can I install these myself? Yes, most installations require only basic tools and reference to the door’s mounting points. Check for bracket compatibility if included.
- Is a two-pack necessary? A two-pack is helpful if you have two doors or want a spare; it helps maintain balanced tension across multiple hinges.
- Will higher weight capacity hurt my door? Using an overly strong lift can make opening and closing harder or stress mounting hardware. Use the recommended range for your door.
- What should I check before buying? Confirm door model, stroke length, load, mounting bracket compatibility, and whether the product includes hardware you need.
