Well,I will basically reiterate what others have said as I pretty much use the
same gear/clothing etc. for cycle and backpacking.In fact I purchase any such
items with such mulifunctionality in mind.Bike tools
,of course,are an exception and Dan gave a good list of the basic essentials.

I can't give you exact weights because I find all scales simply weight too
much.Seriously,just by feel and experience in paring down to essentials I can
say my base load for my tour this holiday(minus food/water/tools but including
panniers/packs/racks/trailers)was less than 15lbs(and my tent and pack are light
but not ultralight).This was my first tour on a mtn. bike and I was actually
going to a destination to backpack so I wore my backpack on my back with most
food/water/tools/clothing.I lashed the tent to the front handlebars and a
bedsheet in place of a sleeping bag in a stufsack lashed to the seat rails(it
was actually too hot for even a sheet so it made an excellent pillow). Of
course,in Fl. I can also keep clothing particularly heavy/bulky items to a
minimum so only took a spare bathing suit/tank top/rainjacket(I backpack in the
same clothing I cycle in and store my bike/tools hidden in the woods while
on-trail) .While I had no racks/panniers/trailers I may consider a light rack in
the future to lash the backpack to,as I do on my touring bike.With a mtn/hybrid
bike you can handle more weight on your back due to the more prone riding
position but as I racked up the miles later in the day it did become one more
thing in addition to the heat etc. to overcome.

But the problem with Fl. touring particularly in summer is the massive amounts
of food and water one must consume to stay hydrated and energized so I usually
carry at least 6 liters of water and plenty of food(for constant snacking).And
the various gatorade/bottled water/cooking oil bottles also take up alot of bulk
as well so I am considering a bladder or hoser or two etc. but my concerns have
been I always like knowing exactly how much water I have left and good or bad
you tend to drink more with bladders so run out faster.I found this out crossing
the everglades with others who ran out of water with the bladders while I had
plenty horded away as usual.

Like others said the trailer,while certainly not much of an obstical with a
mtn/hybrid bike to pull it,will be heavy in itself and is designed for and tends
to encourage you to take heavier loads.One trailer could probably handle at
least two or three ultalight loads (so if it is used in this fashion with the
stronger rider pulling it it may make sense)or in my case I would probably load
it down with 20 liters of water,lol.
