Trickle charging won't help you much beyond keeping batteries up in storage. If you want to keep the batteries up while boondocking indefinitely, you'll need a lot more. For my 220ah battery bank and usage of 25 to 35 amp hours between sundown and sunup, 200 tiltable watts on the roof and a PWM controller works great. But to know if that will work for you, you first need to know how many amp hours you typically use. Judging by how long your batteries last now, I'd guess you would be fine with 200 watts. But it's best to do the math. RV Solar 101
