No problem I have a 14" spare with 15" wheels on my flat bed trailer. The 14s came off another trailer. I look at it like using a doughnut tire on a car. Its a spare to get you out of trouble not to stay on permanently. Don't worry enjoy your trips.
Join Passport America you will get you money back in two days, there are at least 5 Passport America RV parks in Branson and more in the area. We usually stay at Branson's Ozark Country Campground $20 a night with Passport America. That RV park is 3 miles to strip and 8 miles to Silver Dollar City We have not yet been to a bad park in the area but passport saves us $150 or more every trip up to Branson.

I had the same problem. Loose ground wire on the truck connector. It had enough ground to let the brake lights work only two of them. The running lights used more power and worked for a while and quit. It was the connector in the bed so I used the bumper connector. Bought and new connecter to put on did same thing. I traced the wiring down to a loose ground connection on the truck.
We had a smell problem in the bathroom also. It was the toilet were the two half's are joined together. I called Thetford and they sent me a new toilet under warranty. It was a easy fix but took me a few days to find that is were the problem was. Look behind the toilet there is a open area about bowl high off the floor, look in there or take picture with phone found liquid in that area. Just somewhere else to look I thought I had tank problems also but it was the toilet.
My parents travel with two dogs and a cat. When traveling they are in a crate. When stopped the dogs are inside are in a outside pen. The cat is inside or on a leash and they go for walks with the dogs and cat. Strange to see a cat on a leash but it works for them. Cat going in a out of the RV when home and dad is working on it or loading. So cat is ok the RV and its a safe place.
Its a bonding wire. For example, if a storm is coming and you try to refuel with out it you will know why you need it. Mobile fuel needs it because you are not grounded (unless you are plugged into electric power)you want to bond before you put nozzle in tank and start dispensing fuel the fuel falling into tank will cause a buildup of static charge. Service station pumps are grounded and the hose touching the filler neck bonds you to to pump then to ground.
FYI we have been to a RV Park on the Gulf Coast that charges one price under 30 foot and a higher price for over 30. 30amp or 50amp no difference in price. Only park we have every been to that charges like that.
