Help New trailer PDI this week

Any thoughts on using the PDI list linked previously in this thread on the purchase of a used TT. We will be picking up our first trailer, it is only 2 years old and appears (superficially) to be in excellent condition. Obviously there will be some wear and tear on it. I have read up in the forums etc and I think I have a decent idea of how things work and I do not mind taking the time to nit pick. I was thinking that I will make sure that everything is 100% functional ie plumbing, electrical, propane, moving parts etc. What about things like wear items like tires, caulking, awning etc?
Thanks
