Prior to doing so why not fire off an email to the source at Leisure Line and see what they say on the subject. Might save you one big headache if transporting on its side is a no no. Dave is a great guy and will be happy to answer your question(s).
You can reach Dave at Leisure Line via email at [email protected]
or give him or Matt a call at (570) 752-1811
Of course you can also send Dave a PM via this site as well.
