The FIRMAN WT05571 Tri-Fuel Whisper Series Generator provides flexible and reliable power for RVs, camping, home backup, and DIY projects. Its tri-fuel capability allows operation on gasoline, propane, or natural gas at the push of a button, adapting to available fuel without compromising performance.

Delivering up to 6,850 starting watts and 5,500 running watts on gasoline, 6,250 starting watts and 5,000 running watts on propane, and 5,500 starting watts and 4,500 running watts on natural gas, it ensures consistent energy for household devices, RV systems, and power tools.

Designed with portability in mind, this generator features a compact 136.7 lb frame, integrated wheel kit, and folding handle for easy transport. Operating at just 67 dB, it maintains a quiet footprint suitable for residential areas, campsites, and RV parks.

Included accessories such as an engine oil bottle, oil funnel, tool kit, LPG regulator, and quick oil drain make setup and maintenance simple.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.
