What is the difference between the Economy Version and the Standard Easy Cover®? What are the best applications for each?

The two systems operate in the same fashion; arm-style/mouse trap style with spring. However, there are differences in arm material, spring options, size, motors, tarps, and of course pricing.

Arm Material

Economy: Square Profile arms

Standard: Heavy duty "tear drop" profile arms (unbreakable under normal operating conditions).

Spring Option

Economy: Open air side mount springs

Standard: PowerPack (closed) side mount, under mount or underbody springs

Size of Dump Unit

Economy: Only up to 21'

Standard: Up to 40'

Motors

Economy: Superwinch

Standard: Aero Industries exclusive PowerPlus on shorter applications and heavy-duty Superwinch on longer applications

Tarp

Economy: No webbing, Asphalt tarps are made from polypropylene.

Standard: Webbing, Asphalt tarps are made from RFL standard fabric, Option for a weighted tarp

The economy system can be used for most applications up to 21' dump units. However, for heavy duty application, Aero Industries recommends the standard Easy Cover. We have steel and aluminum available in both styles. The wind deflector is an option with the Economy, where the standard comes with a choice of wind deflector or tarp housing. Both kits offer the manual hand crank or the electric motor option.

What is the difference between RFL and polypropylene asphalt tarps?

Quality. RFL is a durable canvas material that is treated for asphalt and polypropylene is a lower grade mesh material. RFL is used on Standard Easy Cover systems and polypropylene is used on Economy Easy Cover systems.
