Just received our new Briggs and Stratton 26KW generator in perfect condition. Ordered on Monday 2/13/2023 from National Supply and delivered on 2/17/2023 via R&L at the scheduled appointment. Driver was super courteous and friendly and went over and above to help me roll the generator into our storage building. Thank you National Supply and Nathan on the chat support for making this a great experience,

Fast and affordable!


Not only did you have the generator I wanted I could find in-stock nowhere else, but it shipped the same day and arrived, undamaged, exactly the day they told me it would. I couldn't be happier. Additionally, the shipper provided a 4-hour window for delivery, which was a very pleasant surprise given the size of the generator.
