i haul my 1955
harley fl pretty much everywhere when i take the airstream. it rides in the back of my pickup, a '00 2500 silverado with an 8 foot box.
here are a couple of tips:
buy a quality ramp, mine is aluminum and folds in half.
get good tiedowns (4), ratchet type are the best. tie the bike off 4 ways!
get "soft ties" they are nylon loops that you can put on your handlebars etc to prevent scratches. they also go around irregular shaped parts.
if your truck does not have sturdy rings install some.
if you use a front wheel chock (i don't) pad the front tire to prevent damage.
haul your bike in neutral, this prevents tranny damage and belt/chain/ sprocket damage.
do NOT let the bike ride on the side stand, haul it perfectly upright secured 4 ways.
when you arrive or depart, look for natural advantages to assist in loading/unloading. backing your truck into even a small depression will aid greatly in the angle of the ramp.
ask for help loading/unloading if possible, i have never run across a situation where a fellow able bodied camper would not lend a hand! (a couple of cold beers don't hurt either!)
and finally, be aware of your new surroundings! for me, after i get somewhere the switch from silverado to vintage harley takes a little adjustment... traffic is different than home, wildlife, road conditions etc.
ps, this is my setup
