I wonder if you might induce screen sag by transporting on it's side.
If you don't want to hire a trucker, how about getting the smallest rental truck?
Here's a discussion on the same subject on another thread:

And then there's this from the following thread:

"The DLP should definitely not be placed on its side and in fact is supposed to remain on the blocks all through the shipping process.
I was fortunate in my purchase from Paul's (an 82740)which was shipped from California to Maine. I had emphasized when I purchased it that it had to go to the second floor of my home and thus definitely required two people to get it set up for me in the home. I also was able to contact first the initial shipping company and then the local company. The latter agreed to have two men do the work which actually required that they have two trucks show up at my home since they only have one driver per truck. I had emphasized with them the necessity of keeping the DLP completely upright, etc. and fortunalely all went well.
While you are at the mercy of the local delivery people who bring the DLP to you, obviously Paul's bears the ultimate responsibility. But, unless you happen to be in a local delivery area for one of these dealers (eg. Walts, Paul's) you run the same risk every time....but hopefully eventually one will get there in one piece."
(Sorry...I'm too tired to edit it!)
Then there's the experience of this guy in Malaysia on Yahoo answers:

If it were me, I would not place it on its side.
