battery tray - location & access
So, on my X160 I can't easily access the spot where my 12V batteries are located (and, of course--batteries have only gotten larger over the years). I don't store my camper at the house, so I must constantly swap out charged batteries. I have some shoulder and bicep injuries, so I'm looking for a better way. (The propane tank takes up a lot of room on the A frame.) Any ideas? (I don't want to go the 6V battery route.) I've researched some aluminum trays that could probably be U-bolted on, but most are too wide for the location (which abuts up against the diamond plating). I do have solar panels, but one can never rely solely on that. Thanks.
