The tire size we show as standard on the 2007 Chevrolet Silverado Classic is 245/70-17. For this tire size the Konig chains you referenced, K-Summit Diamond Pattern chains # TH02230K77, are a compatible fit. However, please note that the other chains referenced, the Pewag Brenta-C 4X4 Snow Tire Chains # PWXMR81V, are not a fit for 245/70-17 tires.
When it comes to tire chains the auto maker gets the final word on what is compatible and safe. My suggestion is to review your owner's manual... view full answer...
There are differences; the EZ Coupler RV Sewer Hose # D04-0113 is 10' and has both a 3" bayonet fitting and swivel fitting while the Valterra # D04-0111 is 5' and has a pair of 3" bayonet fittings.
Those hoses do have the same 3" diameter, 18-mil vinyl construction and are red in color. view full answer...
