Where I live is mostly flat and am running 46x16. Hills really wouldn't scare me too much (I still have brakes)
The biggest limiting factor I have found in towing is that there is a point where the trailer will unload my front wheel and then my steering becomes more of a suggestion (about 100+ lbs... I am routinely exceeding the suggested limits)
Here is an article about ratios. It's really about finding the least worst setup for your needs; easier hill climbs means more spinning when going down hills and lower top speed.

I read somewhere that the safe cargo limit for a bike trailer is approx. half the weight of the rider + bike.
So, if you weigh 160lbs, and your bike is 30lbs, the max recommended weight of the trailer and cargo should not exceed 95lbs.
I've hauled over 115lbs with my bike (loaded panniers + trailer), but never exceed 65lbs in the trailer due to size/volume limits of the trailer itself.
But I do find that heavy weight causes the trailer to "push" the bike in ways that feel unsettling. 100+ lbs would make me uneasy! It's amazing that you're doing it! Kudos!
Thanks for that! I didn't know the math to work that out!
The pushing is not as scary because I don't exceed 10mph when that heavy of a trailer and because I can resist that pushing quite a bit with the pedals... which is a great feeling.
