I've used garden hoses for 40 years out here. Some last a year or two - others, a while longer. The very best are commercial, all rubber, black, garden hoses. I've got a couple of those and they are over 25 years old. Still as good as when purchased.
I think you will find that gravity and a GOOD hose will provide all the water you need.
I have no idea how long it will be until you have a functioning well on your property. I would limit your plantings until that time. You will soon find that what you are proposing - gets old. Load the container on your truck - fill it - transport it to your property - get it off the truck - go about your watering. This will go on until you get a well and some type of distribution system.
Also - check to see what type of "varmints" you might have on your property. I have pocket gophers. About 1/5 the size of a ground hog - but total HELL on new plantings. For any type of a tree - consider using gopher cages if you have gophers.
No matter what I plant on my property - tree, bush, flowers, garden - I have to make provisions to exclude pocket gophers.
