After months of YouTube watching, gathering opinions, and comparing prices I went with HornBlasters 2485K Nightmare Horn kit with dual tanks on a spare tire delete bracket. I have never hooked up tanks before so this was my very first attempt at install. The bracket fit perfectly on my lifted F-350 SRW. The horns hang a little lower than the spare did but still not obvious as they sit behind the tow hitch. Mounting everything to the tanks and bracket was simple enough, every part needed was supplied. The wiring diagram was a little confusing, but anyone with deductive reasoning and simple electrical knowledge could figure it out. Total install took me about 4.5 hours, but I am also a perfectionist. I plan on re reviewing this product after having it on for 6 months or so, but I have no worries! Thank you HornBlasters!
