I hesitated to post this as it is not what you will want to hear, It is however, something you may want to think about and just my opinion.
Buying or Renting a Trailer to move a 48 patio will get expensive and will always be a pain. In the beginning it will be fun, and if you don't do it often I'm sure it will not be an issue. However, if you plan to compete often, (several times a season), moving that size cooker will get old fast especially at the end of a contest and after staying up all night to feed the fire box every half hour. This is excluding the effect of bad weather (rain), and the possibility of getting stuck in the mud.
If you are planning on competing often you may want to think about a couple of WSM, or UDS, or getting a Lang on a trailer.
We compete with a Lang 84 on a Trailer and with that we are very tired at the end.
My comments are well intended, honest, and again, just my two cents.
Good luck.
