For exhaustion, you can also spam lesser restoration spells, scrolls and potions. First cast removes fatigue, second cast removes exhausted. Since it is a lvl1 paladin spell, you also get infinite cast via trickster.
BTW all companions can tank unfair with 80+ AC and a bunch of immunities with the right setup. Seelah, camellia and wenduag/lann are the best bets though, since they only have 1 level at their base class. Camellia is good at this even with her base class, but a tank without any other utility is a no go for unfair imo.
