Since the distance from alternator to trailer connector to battery, voltage/amps at the trailer battery will be less than at the truck battery. However, the lifepo battery does have different ‘expectations’ than a lead acid battery for charging. You can use the existing truck feed and drop a DC2DC charger in line right at the trailer battery.
In your case you mentioned you don’t need the truck recharge anyways. So pulling the fuse is an option. A lifepo-compatible charger is a fraction of the cost of the lifepo battery though.
I don’t see why you couldn’t just depend on solar as you stated. But the ‘cost’ of vehicle charging to the trailer is basically nothing after you by the DC2DC so why not? Fully charged is ready. Drive it use it for a while with the fuse pulled. If you wind up needing vehicle charging you know what to do.
