My husband and I have had two A Frames. We first had an Aliner Classic (12 foot box), but we found it to be too small. We sold it and bought our current Aliner Ranger 15 (15 foot box). We like it a lot. It tows great and sets up in a minute. If our budget would allow, we would have gotten an Aliner Expedition with two dormers.
You need to decide whether or not you can exist in a small space. We're outside a lot, so it's not a problem for us. We have a 60x80 queen bed, a large dinette (makes into a very roomy single bed, when needed), a Cool Cat heat pump/ac unit (central a/c and heat with digital thermostat), sink, hot water, fridge, stove, microwave, cassette potty, outside shower, and several cabinets for storage. We also bring along slide out Sterlite drawers for clothes and dry goods, an easy up, a camp kitchen for cooking outside (complete with electric frying pan and small electric oven, and an electric ice maker. We bring a t.v. if we'll be in a place with a cable connection (Aliners don't have t.v. antennas, but they have cable connection). Yeah, we like our creature comforts!
No, don't do it, especially a 15 footer (Aliner Ranger 15 or Expedition). The hitch weight will exceed your capability, even on the older models. You don't want the tail wagging the dog. You need a minimum of 3500 lb. tow capacity to tow a 12 footer, and 4500 to comfortably tow an Aliner Ranger 15 or Expedition. Remember, it's not just the weight of the camper, but the weight of the battery, propane, water (if carried in fresh water tank), the hitch, all your stuff, and the weight of the passengers, too, that you have to take into consideration.
Please look at something like the Toyota Highlander, Ford Explorer, any 6 cylinder truck (Tacoma, Frontier), Chevy Traverse, Honda Pilot 4WD, GMC Acadia, etc. Make sure any of these vehicles has a tow package, or else they aren't up to the task either.
Older dogs rock! I'm NOT a puppy person whatsoever. We have two adopted rescues, Maddie and Kramer. Maddie was 2-3 when we adopted her four years ago, and Kramer was about a year old when we adopted him earlier this year (we were told he was older and were shocked when we found out he was still a baby!). In the past, I've adopted a 4 year old lab (he lived to be 11 yrs. old) and also a 9 year old Golden (who lived to be 17!), as well as several middle-aged to senior boxers (4-9 years old). We've also fostered senior dogs, and I LOVE them! The worst dogs we've had at the beginning are a young beagle/bassett and a 4-5 month old black lab (although the black lab turned out to be one of the BEST dogs we've ever had, once he matured, around age 4 and who lived to be 14.5 years old!).
I'd aim for a 12-30 pound dog, anywhere between 3-5 years old - perfect in my mind.
I use Nextguard on my dogs, and it works well, even down here in the deep south. However, it is expensive and must be used with caution with dogs prone to seizures. I started using it when Frontline Plus quit working here.
Look behind the storage drawers and you can see the plastic shoe containers at the foot of the bed. You can also see that we've hung holders for micro fiber wash cloths (we use to dry hands and dishes), as well as a hanging paper towel holder. There's also some room above the drawers to store other small items.
I have an Aliner Ranger 15 with potty (same size/counter space as the Expedition). We keep our hanging clothes on a clothes hanging rod in our SUV and get out what we need the night before, hanging them from one of the inside latches. We keep folding clothes and dry goods in slide out Sterlite bins that we stack on the counter next to the potty (we have a split counter so we can access the potty without lifting the whole counter). They store nicely under the dinette table during transit. We keep socks and underwear, plus a container of toiletries in plastic shoe boxes at the foot of the bed. Four of them fit between the end of the mattress and the camper wall on their sides.
Some people hang an extendable painter's pole at the peak of the triangles when setting up to hang things from (hang up clothes, towels, hooks, etc.).

I used to think I was pill-giver extraordinaire UNTIL I fostered my first shih-tsu. Holy Moly! It was like trying to give medication to the Tazmanian Devil! Those little teeth clamp down hard, and they don't have as large of a gap between their front teeth and their molars as a larger dog has, which helps when prying the dog's mouth open and holding it open.
I hope you can find something that works. Does the medication come in liquid form? I was able to slip a small syringe (without needle, of course) into the mouth and give liquid meds much easier.
I left my vet several years ago after the practice went corporate. They started pushing expensive care packages, most of which I wasn't interested in. They also replaced the front desk personnel, who then had no clue who I was EVERY time I went in. asking me what my name was EVERY time. The previous lady always greeted me with a smile, knew who I was, and knew my dog's name.
I changed to a much smaller practice a few years ago with a good vet, but now this practice is starting down the same path - so disheartening. I find myself fending off services/packages I know I don't need. At least the front office staff hasn't changed and knows who I am. The vet is still very caring and good, so I stay.
We have a 2015 Aliner Ranger 15 (15 foot box; 18 feet total), which I think of as a PUP, especially if booking a site that says "Tent, Pop Up, or Camping Vans Only". We love ours - it fits almost anywhere, and tows like a PUP. We pull it with our 2010 Nissan Pathfinder with no problems at all. It weighs around 2100 lb. dry, and it can be pulled easily with any vehicle that has a 4000 lb.+ towing capacity. Aliners are lighter than the other brands, due to their construction materials (also less impervious to water), which is why we chose this brand, despite paying a bit more for it.
The Aliner Ranger 15 and the Aliner Expedition have a taller ceiling than other models of any brand, so they would be good for a tall person. They are also 3 feet longer than other models of any brand.
We have the Cool Cat and LOVE it! It has an 11.5k a/c (I think), with vents and a digital thermostat, just like at home. You can also order a propane furnace so you can use it without electricity, but since we never boondock, we skipped that option. The heat pump provides plenty of a/c or heat, depending on the setting you put it on. Since we do most of our camping in GA and FL, this is important. We sold our Aliner Classic (12 foot box; 15 feet total) that had the 5k window a/c - it just didn't cut it in southern heat.
To gather additional information, I suggest that you join the Facebook group: A Frame Campers: Aliner, Chalet, Rockwood/Flagstaff, Starcraft.... It's a great group with helpful people (some salty ones, too - lol).
