I have a 25 gallon Fimco boom sprayer that was intended for an ATV rack. I used to bolt it down in the back of a small trailer, and it worked fine, but was a pain to set up and remove so I could still use my trailer. My son welded up a slick cart for it so now it's permanently mounted to that. When fitting it to that cart, one of the mounting bolt holes was slightly off and stressed the nut insert in the tank, cracking it. Luckily I found the exact tank still available at AgriSupply so it was an easy swap.
After rebuilding then replacing the pump and wand over the years, I learned that RV antifreeze wasn't the best option for winter storage. Now I remove both the hand wand and the pump and store them in my basement to protect from freeze damage. Not sure if that affects you in your location.
I also had some issues with algae growth in the lines and tips when stored for months. Now I pop off the tips and screens, drop them in a clear peanut butter jar with some water and dish soap, and shake them up to clean. After a couple rinses with clean water, and drain the water and leave them in the jar for storage (with a lose lid so they dry). That's worked great for several years now. It's nice to insert the screens and tips and off I go, knowing there won't be a gooped up mess with plugged tips and a full tank of chemicals. That happened twice before I started removing the tips after use.
Oh, I noticed the stiff boom hinge on yours. I think you can loosen the hinge bolts so it moves freely. Mine works great, springing back around trees and posts in tight areas.
