Not enough room over my toolbox for the firewood, the bike rack sits over the top, and there is a small solar panel on the toolbox too. I might get one bag of wood in front of the spare behind the stone guard.
Foam mats for protection are a good idea, think I will run with that. I was thinking I'd get a pool noodle and zip tie it onto the panel frame. Foam mats will be better for the firewood.
Will put some slots in the solar panel frame and strap through there to hold it down without covering the cells. For the return trip I might slip it under the mattress as a good suggestion, but I'm not keen on unpacking the tent to do so before leaving!
I'm going to have to rethink for future trips.
