Nice little 19' Conquest BH. Congrats on the new TT and even at a more discounted price!
If you are keeping your van as the primary Tv you will definitely want an auxiliary Trans cooler, gauge is optional but a good idea.it is normal for if to sty in 4th since more than likely 5th is overdrive. I would also recommend at keeping 65mph as your max speed based on the fact tht almost all ST trailer tires are only rated for max of 65 mph.
Take your time and enjoy the new TT! I hope you and your family enjoy using it a great deal!
