Thought I would post my solution to my own topic in the off chance that it helps someone down the road.
After considering QCMan's suggestion, I looked in the propane tank area for a mounting spot for said Booster. Pulling the propane tank cover and looking that area over, I really did not find a spot where I could securely mount the booster (I don't know if the TST booster is different than TireMinder). While there, I pulled the cover off of one of my batteries to check fluid level in my lead-acid battery (discovered they are maintenance free). I noticed that there was plenty of space on top of the battery, under the cover. I connected the Booster and tried it sitting on top of the battery, it worked well. I cut a slot into a thick piece of foam rubber so that the cover would hold the foam rubber encased booster in place. It seems secure in place. Still plenty of room under the rest of the cover to allow for battery/air circulation. They are maintenance free batteries so other than having room to dissipate heat, there should not be an issue. I will for certain, remove the booster during winter storage. We are considering this will work. I will post again later if we experience electrical interference with the booster mounted in this place.
Safe travels y'all.
