Direct answer to OP question, yes you can run the truck for a short time each morning. (Especially if the truck is mechanically in good enough shape to tow your TT around.)
However I agree with others on this forum in two regards.
1. Asking a question, any question, is what this forum is all about, so there are no real dumb questions. Ask away, and most here will try to answer. Some may ask for more details, and everyone has a different amount of ability to ask their questions without sounding arrogant, or dismissive. Some are pretty good at asking for more details without causing any negativity, some not so much.
2. There are most likely a couple better means to the ends you are looking for. In other words, what you are trying to do may be doable as you questioned, but there are most likely better solutions. Several have been presented already.
Have fun. Good luck.
