At our last RV show GY tires were touted where whenever they are used. I also was not impressed by the imitation fire place heaters. Of course I am not impressed buy gas logs in home fire places either.
I had an interesting talk with one of the dealers. He knew I was not buying so we chatted about slides and mods. From the dealers perspective, if you modify your TT or you buy a TT without a slide; you have better plan on keeping it for a long time.
Dealer want to turn over their new and used inventory and currently buyer want slides and like new conditions.
