Spec Comparison: Cap50 vs Cap66
Compatible Truck
The FLATED Air-Topper CAP50 is designed specifically for mid-size trucks with 5-foot beds. Its model code, AIRCAP-MIDS1-24, reflects this narrower focus. In contrast, the CAP66 targets full-size vehicles. It fits 1500 standard beds and 2500/3500 short beds. This broader compatibility makes it suitable for larger work trucks and heavy-duty pickups. You must match your truck class to the correct model. Choosing the wrong size compromises fit and security. The CAP66 serves a wider range of larger vehicles, while the CAP50 is strictly for smaller mid-size frames.
Bed Size
Bed length determines which cover you need. The CAP50 covers a 5-foot bed. This is a compact size, ideal for maneuvering in tight spaces. The CAP66 covers beds ranging from 6 feet 5 inches to 6 feet 9 inches. This significant length difference accommodates standard and short beds on full-size trucks. If you have a 5-foot bed, the CAP66 will not fit. If you have a 6.5-foot bed, the CAP50 will leave your cargo exposed. Select the model that matches your exact bed dimensions to ensure full coverage.
Construction Material
The CAP66 specifies its material as military-grade PVC-coated drop-stitch. This construction is engineered for strength, durability, and stability during highway driving. It handles changing weather conditions and heavy loads. The CAP50 lists two-chamber construction but does not detail the specific fabric type or coating in the provided data. Both are inflatable, but the CAP66 offers explicit details on its high-performance material. This suggests a focus on rugged utility for the larger model. You should verify the exact material specs for the CAP50 if durability is a primary concern.
Profile Style
The CAP66 is designed to create a sleek cab-level profile. It sits low, matching the height of the truck cab. This provides a streamlined look and secure storage for gear. The CAP50 is described as an inflatable truck cap bed cover but lacks specific profile details in the data. Both offer a covered storage solution. However, the CAP66 explicitly highlights its low-profile aesthetic. This design choice may appeal to users who prefer a less bulky appearance. The CAP50 likely follows a similar low-profile inflatable design, but the CAP66 makes this a key feature.
Installation Method
The CAP66 features tool-free installation with no drilling required. It can be installed or removed in minutes using included hardware. This allows for easy storage in a closet or garage. The CAP50 is an inflatable cover, which implies a similar mounting system, but specific installation details are not listed in the data. Both products avoid permanent modifications. However, the CAP66 explicitly guarantees a no-drill, tool-free process. This transparency helps you plan your setup. You should check the CAP50 manual for its specific mounting requirements to ensure compatibility with your truck bed.
Which FLATED Air-Topper Fits Your Truck
Mid-size truck owners with 5ft beds
The CAP50 is built specifically for mid-size trucks with 5-foot beds. Its model code, AIRCAP-MIDS1-24, confirms this narrow focus. You get a two-chamber inflatable cover that matches your truck dimensions exactly. This ensures a proper fit without the need for adapters or modifications. It provides secure storage tailored to your shorter bed length.
Full-size 1500 owners needing standard bed cover
The CAP66 fits full-size 1500 standard beds and 2500/3500 short beds. It covers lengths from 6.5 to 6.9 feet. You get military-grade PVC-coated drop-stitch material for strength. The design creates a sleek cab-level profile. This model, AIRCAP-STND1-24, offers the right coverage for your larger vehicle without gaps or overhang issues.
Drivers wanting tool-free installation and easy storage
The CAP66 allows installation in minutes with no drilling or special tools. It includes everything needed to inflate and mount. Unlike fiberglass shells, it deflates and rolls up for closet storage. You avoid permanent modifications to your truck. This flexibility lets you remove the cover when you do not need the extra cargo space.

Frequently asked questions
Can the FLATED Air-Topper CAP50 fit a full-size truck?
No. The CAP50 is designed exclusively for mid-size trucks with 5-foot beds. Its model code AIRCAP-MIDS1-24 confirms this specific fitment. If you own a full-size truck, this cover will not match your bed dimensions. You need the CAP66 for larger vehicles.
What truck bed lengths does the CAP66 cover?
The CAP66 fits full-size trucks with bed lengths between 6.5 and 6.9 feet. It is suitable for 1500 standard beds and 2500 or 3500 short beds. This model provides a secure, removable storage solution for these specific full-size truck configurations.
Is the CAP50 suitable for a 6-foot bed?
No. The CAP50 is built specifically for 5-foot beds only. It will not fit a 6-foot bed. You must choose the CAP66 if your truck has a bed length of 6.5 to 6.9 feet. Using the wrong size compromises security and fit.
Do both covers use an inflatable design?
Yes. Both the CAP50 and CAP66 utilize an inflatable structure. This design allows you to deflate the covers for compact storage when not in use. You get a practical alternative to hard caps without the bulk of permanent installations.
Which model is better for a 1500 truck?
The CAP66 is the correct choice for a 1500 truck. It fits the standard bed length of 6.5 to 6.9 feet. The CAP50 is only for mid-size trucks with 5-foot beds. Selecting the CAP66 ensures proper coverage and security for your vehicle.
Can I use the CAP50 on a 2500 truck?
No. The CAP50 is restricted to mid-size trucks with 5-foot beds. A 2500 truck typically has a larger bed. You need the CAP66, which fits 2500 short beds. Using the CAP50 would result in an improper fit and potential security issues.
