Actually, OP has an A-frame, not a TT.
Care for the electric lift is either spend money on replacements. Under very good conditions (stored inside, protected from rain and dust), the electric lift is good for 2-3 years. Stored outside, and used in the rain or dust storms, electric lift life is less than a year. Water, dirt gets past the shaft seal and gums up the gear box and or motor. You can take apart clean and lube every 12 months, replace on failure, or change to gas struts. Lots of threads in the A-frame forum about that.
Battery install is generic for campers and travel trailers.
You will find a lot more info in the A-frame forum.
