(Not to take away Roo's thunder, but I had already been testing out the bight through the Span Loop idea.)
I assure you that I had no thunder to steal.  Pulling a bight through a midline loop is a procedure that's quite a bit older than me.   ;)

Well, I thought I explained what infinite means pretty well, but I guess not.
Here goes another try.  "Infinite" simply means long;
I don't want to cut the rope; also, I don't want to sit there and
 run the long rope through the [eye] of the Trucker.

But doesn't Roo's remark apply generally, to anything
that forms an eye to be used qua pulley sheave ...

...

Now, a plausibly practical circumstance in which your
"infinite-rope" problem has some merit is where indeed
  (and perhaps this is just what you meant in the OP)
you've  a long rope and so care to toss only a big bight
over the truck's cargo and on the flip side put in two
trucker's hitches --of course, lacking access to the end.
This seems not at all implausible --and so intriguing that many
PracticalKnotters will be jumping up from their keyboards
immediately to go start casting long bights in the night!!
 ;)

That last solution is nice, but I'd probably rather send the two ends
over the Truck while hitching the bight at the initial anchor.
Or maybe that's what you meant.
No, you wouldn't : tossing 50' of rope --which is of
course excessive-- would be a PITA (and tossing an
"infinite" rope would be too hard!); rather, you'd
guesstimate your needed amount, toss the bight,
then run you still-on-tossing-side line under a hook
to the next hook and toss over a 2nd bight enough
for bindings #3 & 4 (long bed of hay bales).  (One
might be able to "guesstimate" pretty well by looking
beneath the truck bed to see what amount of line
is lying on the ground; then one could tie off the
tossing-side with clove hitch and run the line
to the next hooks & toss.)

Now, I've seen lobster boats where they bind down
stacked pots, but do so one-line-per, I think, no need
for the complications of a single line, which entails
dependence and inflexibility.  (Hmmm, I might have
photos of such securing.)

Well, thank you for not describing this sooner, despite all the Bell Ringer debates in the other thread!
I wasn't following the other thread.  It was becoming too long and messy.

What kind of hitch would you use to secure the bight
if the anchor is a ring/bar, as opposed to a hook?

(If it's a hook, I'd probably secure the bight by using a Pile.)

Back to this infinite-rope probem, which seems to be veering
too far afield from practicality (were one to really be using
a long line, likely one would engineer the system to have
several short hauling lines to put in the tightening parts,
with e.g. Prusik hitches of a sort (one end the hauling
end, the other tied into the eye-sheave) --kinda like the
use of short stout bits of rope for the eyes, as introduced
by Knot4U elsewhere).

The question's answer "if a hook" indicates tying off the
non-tightening side, but that's an easier problem than
tying off --to a ring(!)-- the tensioning side, which is
also a bight!  (For the former, I'd think that a turn +
half-hitch + slip-knot would suffice, for quickness
and material efficiency; or a fully doubled-line two
half-hitches (clove noose)
).)

One would need to bring the bight up through the ring
and then use some eye-formation that encompasses
the bight AND the infinite end --building a theoretical
4:1 system (which will actually be maybe 1.7:1).  With
luck and some care, one should get the versatackle
locking of the bight part atop the hauled infinitEnd,
and that should make it easier to tie off.  (Note that
any slackening from tying off will have to be distributed
over the 4 parts below the sheave-eye, so will be much
mitigated in overall loosening effect --another plus.)

Conceivably, one would simply run the end (still
a bight tossed from over the load) to the next ring
and tie it off there.  One could bring a bight through
the next ring and then form a bight in the going-away
line to tie a sheet bend to the bight tip.
