Thanks again. You may be right in me overthinking, however, i am still a little confused on what your saying.

The truck is not being split, it will be used 100% for LLC. Another personal vehicle, not truck, will be used for S- corporations. It appears your responses are all geared toward the truck being used for all separate entities; if that is taken out shouldn't the answer change?  

Basically your saying regardless of the intended use of truck, it could be used as personal vehicle for S-Corp, as such, truck will be considered mixed use. Am i correct? and reported like below:

LLC should report vehicle, but not at 100%
S-corp 1- reimburse employee for personal use.
S-corp 2- reimburse employee for personal use.

I thought this question to really be an expansion or slight modification of another often approached question pertaining to S-Corps; which is, "should i put vehicle in my name and get reimbursed" or "put vehicle in that of the company". This is a very common question, and we run the cost/benefit of each. One benefit in the reimbursement scenario is the favorable effect on reasonable compensation.

I appreciate your time in all your responses. Thank you!
