few things to note here. the jump packs regardless of manufacturer will always say to discharge unit if storing for more than 3 months, or will say to discharge unit every 3 months to maintain the battery inside. the ah of a battery isnt the end all be all for batteries. my oem battery lasted me 3 months because of the amount of current draw from my sound system. had it replaced under warranty thinking it was a fluke. new battery lasted about 3 months..... swapped it out for an optima yellow top and the battery lasted 4 years before crapping out. put in another and it lasted about 4 years as well. now on my 3rd yellow top and its been in year or so. the cca and the ability to be drained and recharged without capacity loss is why i keep going with gel cell batteries. so while the ah of the oem might be more, it can sometimes not be enough cca, after being partially drained, to start your truck. the lithium batteries are awesome. expensive, but awesome. problem is, as stated above, they dont like cold weather and can be an expensive paperweight if they get too cold.
just take out your moonroof and put solar panels. until skynet takes over and we darken the skies, it will always work. might take a while, but will work.
