Please Assist - Multiple Conversion Questions

Feels like I'm bursting into the door with a monster truck with this first post. I've been a long time lurker and watch/read everything I can on conversions. I have a few questions that have been bugging me regarding the conversion of my enclosed trailer. I'd appreciate any help you could give me.
backstory - 7W x 16L x 8H v-nose double axle. Will be moving to an RV park for 3 years and then possibly moving across the country. Each RV park space has 30 or 50 amp power, water, and full sewer access.
Average high in August is 90f, Average low in January is 23f.
1. Should i go with a mini-split or window A/C. I'd like to utilize the 30amp power due to cost (100 less/month). For the winter i'll have a grizzly wood stove. I've read that most mini-splits are only good for temperatures above 30. For times when i'm away from home and waiting on the wood stove to get going would it be better to have the mini-split assisting or just get a couple electric heaters or buddy propane heater?
2. In regards to awning patios. Are they worth the price? Do they stand the test of time if utilized year round? I'd like the ability to be outside through the nicer months in a screened and rain protected atmosphere when i can. I'll also have my motorcycle with me and it would be nice to have the motorcycle under the patio area (and put it in storage through the winter).
3. White/grey tanks - for the first 3 years the trailer will not move. Is it worth it to install the tanks now or is there a way i can safely have the grey go straight out the trailer to the sewer without having much issue w/ smell.
4. Insulation - I've already installed 3/4" insulation in the wall ribs/ceiling and expand foamed between the ribs. From what i've read it would be benificial to install more. Would the best route be to install (for example) 1 inch deep x 3 inch wide wood on top of the current ribs and install some 1 inch insulation and rewall the trailer? Was thinking the wood would insulate the metal better.
5. Dogs - I currently have 2 dogs. One is 30pds, the other is 15 pds. The only time I'll be away from the trailer is when at school or shopping. As long as I kennel them and take them on lots of walks when i'm home, does anyone see a problem with keeping dogs in such a small space?
Electric items i'd like to utilize (not listed above)- microwave, water line warmers in the winter, laptop, refrig (haven't decided on apartment or economy power), security system with TV, couple led lights.
Thank you for reading this short novel, looking forward to the responses. Hoping to remove a little anxiety i'm feeling in regards to choices.
