You will probably need to reinforce the pallet if you use a preexisting one. Make sure it's joined underneath and on top. Leave places so you can strap it down well. Pallet wrap it if it's going into storage, but strap it down as well, at least when moving it. A pallet jack might help to get it up on the pallet, but I wouldn't recommend trying to get it on a trailer with a pallet jack. That's asking for trouble. See if you can borrow a pallet jack and forklift or trade out some spots for services rendered.
