We've got these - https://smile.amazon.com/gp/product/B00EVNQ3XA/ref=oh_aui_search_asin_title?ie=UTF8&th=1 along with a number of the 20 dollar canvas foldups from Wally World or wherever we went when I realized we left ours at home yet again. That Picnic Time looks great but has too much stuff with it. I do need to find something similar that works with a regular height table outside the rv when I'm on the laptop or the like. Get really tired if being hunched forward in the canvas ones or just being stuck inside at the dining table.
I have been lucky the last few years, I've picked up enough left at the track and just tossed them in the rv in case the owners asked about them to offset the ones that have fallen apart so no new purchases for a bit
For the same money I would get 2 of these instead http://www.kermitchair.com/products/ They used to sponser the local MSF classes in TN, not sure if thats still the case but they are made in the USA and really good quality.
When I raced bicyles, and did Tri, it was 'Oakley- Factory Pilots'! They were awesome. Haven't worn them in decades now. Not sure if I ever had an Oakley sticker on my vehicle though- I was deprived
