I'm a full time RVer and travel a lot! If you are going to camp nightly at a KOA, it will take you a very long time to start saving money over hotels. KOA is a camping destination, not a base camp for the surrounding area. It's very expensive because part of the fee goes to paying for the camp store, the pool, the little game room, the WIFI repeaters, the dog park, the kid's playground equipment, etc. etc. etc. They are set up to maximize profit for the owner, which means the sites are packed in as close to each other as possible. That's great if you and a buddy are taking the families camping for the weekend in your RVs. They are wonderful for that! They aren't so great for saving money while traveling.
If you plan to stay in places like KOAs, you'd be better off just skipping the tent and getting a hotel room. There are $50 a night hotels/motels practically everywhere if you just need a place to shower and sleep. Going with tent camping means you'll need a tent, and sleeping bag, etc. Those costs add up. They also take up room on your bike, which is at a premium already on a Speed Triple.
You certainly can go motorcycle camping if you want, but do it because you want to go camping, not to save money.
