enclosed trailer likes
Used a three bike open trailer for a few years, but finally sold it and bought the enclosed trailer, 7x16. Hauls all of my family's stuff plus all my buddy's bikes and their kids bikes. Yep, overkill.
Biggest advantages to even a smaller enclosed trailer that I like are:
1) never have to worry "what if a tie down breaks" (probably will never happen but was always in the back of my mind)
2) riding all day, get back to the pickup in inclement weather, just open the trailer and change inside, nice and dry, or out of the blazing sun for that matter.
3) headed home, we are all hungry, wow Chili's looks good, now don't have to lock bikes or worry about gear in the bed of the truck being stolen.
4) now arrive home from riding all day in the mountains/desert, it's 2130 hrs, I'm tired, just park the trailer. No unloading muddy bikes or stinky gear tonight, it can wait for another day.
5) oh, and Shang, it's cheaper than a pickup
. You will use it for 10 years, and sell it for near what you paid for it. Good investment
