Pulling my Toad for the First Time!! Couple of questions

With our Vue, we redo the engine warm-up in the morning. Check your manual but believe it can be important and if not necessary, I FEEL better. We can and do sometimes leave the car hooked up. New RV sits nigher and so I simply drop the car end tow bars off before leveling the coach. Again, better safe than really sorry. Saves time as all we have to do is reattach the two two bars in the AM.
Happy towing! It will all become easier after a few times towing this one.
