Straps are long, could wrap around camper and forks is they're a little short.
The camper hangs off the back by 17", lift it then block and get forks under. Can strap it against forklift so it doesn't tip forward with second lift.
Worse comes to worst I'll get a piece of plywood to put under on first lift and a pipe under that to roll it forward. Wouldn't want to roll it on pipe, or similar, on the bare belly of the fiberglass.
If that doesn't make sense I understand.
