I think you will find putting everything on a single battery was a very very bad idea, very quickly......... your TM needs its own battery or batteries depending on how you use it.
They also need to be recharged immediately after each day on the water.....Its entirely feasible to survive with a single 12V off-board/portable charger, you really don't need a expensive on-board charger. Just make sure it has electronic controls and is designed for the type of batteries in your boat. I actually have two portable chargers (its nice to have a backup) that are capable of charging all three type's of batterries- sealed-no maintenance (AGM a.k.a. VRLA), wet cell or gell cell (not common for marine use). The upside to using portable charger(s) is I can also charge my veheicle and other batteries as well, that's pretty difficult with a on-board charger.
Yes, on-board chargers are convenient, no fuss, etc.... But, I think if you have limited budget you can get more bang for your money with a portable charger.
Have fun!

We didn't have everything on one battery, we had the trolling motor on it's own battery and the the engine and electronics on another battery. I do know that my father waited until the night before going out to charge both of the batteries, which was usually a week between trips but sometimes up to three weeks. So lesson learned that they need to be charged right away. What I was trying to get at though was if one had to make a choice, would it be better to buy a battery and charger, or two batteries for the trolling motor and run them in parallel.
