When we used tow dolly I .had spare in bay under the coach. I also carried a small floor jack and 4 way tire iron. Never used the spare. Pulled out the floor jack to help a guy with flat on enclosed trailer. His jack for his pickup was too tall. Also lug nuts on trailer were larger than pickup. Floor jack was gold in that case. 4 way as well. Both about 60.00 at Harbor Freight.
