Pick the Gunner G1 if car travel safety is the priority: its Small, Medium and Intermediate sizes are listed by the Center for Pet Safety, and Gunner backs it with a lifetime warranty. Pick the Impact Collapsible if you want a strong aluminum crate that folds flat for storage and travel, and don't need a crash-safety listing.
The central trade-off
Car safety. The Center for Pet Safety lists Gunner G1 Small, Medium and Intermediate. We found no crash documentation for the Impact Collapsible.
Storage. Impact's aluminum crate folds flat; the rotomolded Gunner does not.
Price and warranty. Gunner lists from $550 with a lifetime warranty; Impact lists at $760 (we saw $592.80 on sale).
