I know 3 couples (all Wingsters) with Unigo trailers. All love them. Special hitches required. Matching his/hers western wear seem mandatory too.
That's a Wing thing right...not a unigo thing?
They're interdependent. if you can't pack enough stuff on the FJR for 2 people for 3 weeks without a trailer, you might as well be riding a Wing. it's a bike trip not an RV vacation.
1. Your riding gear is worn: get gear that's vented and water resistant. no need to pack other riding stuff. open/close the vents as heat/wet happen.
2. Street clothes are for the destination, since the trip to is always done in riding gear. after all, you don't stop along the way for anything more than gas and a pee until your destination therefore street clothes aren't needed until then. Ride until your ready to sleep, stop & sleep, awake and ride some more.
3. Unmentionables (3 days worth). Stop every 3rd day and either buy more or do laundry.
4. Street clothes for the destination. See 2 above. Enough for 3 days. Your t-shirts double as your under-jacket gear so don't pack 6 days worth. 2 pairs of jeans max and alternate days. Wear twice then wash or... every 3rd day toss and buy more or do laundry. 1 pair of gym shorts that pack small (for laundry day). Underarmor long (thin) shorts work well but LDComfort works better and is the cat's ass for under your riding gear. 1 pair of street shoes... sandals if you can get away with it. If not, then deck or other low top sneakers that pack flat and small. [1]
5. Sundries. His & hers all pack small: travel tooth brush, bic razor, travel tooth paste (share 1). done! feminine stuff can be packed for 1 additional day and restocked along the way. Find the backpacking version of anything you need. It will be designed to pack small and light; exactly what's needed. Avoid camping when 2 up. It takes space and weight, unless you both agree on rustic with cold meals, it will mean more space and weight to haul. It will take a long time to recoup your investment in many camping investments unless someone insists on 3 star hotels. [2]
When done, you each get 1 saddle bag and share the top box (helmets, gloves, etc. when stopping to eat... because we don't stop for anything else until sleeping or at the destination. remember #2)?
This is from someone who watched his friends (for decades) fail to grasp the difference between a bike trip and an RV trip to the point that Wing storage wasn't enough and it spilled over into trailers (1 and 2 wheel and even those that had hidden houses inside them waiting to pop up... with air conditioners).
Stop the madness!
BTW: Of those I knew who had pulled Bushtech and other trailers and moved to the Unigo, they liked it's handling through the technical stuff better. if you get one, get the properly designed hitch for it too. It's down right dangerous if you use a generic one as generics won't lock it in place with the chassis of the bike.
[1] Matching western wear is optional but not recommended. Matching clown pants is worse.
[2] Hair dryers and like items are inappropriate for bike trips. They are bulky and a clear indication that the person insisting on the item doesn't understand the type of trip they're taking. Use the one at the hotel/motel. Include cowboy boots, dress clothes, multiple pairs of shoes [3], or more than 3 days of street clothes in the list of whacky ideas not worth taking with you.
[3] The right choice in riding boots can double as street shoes so no other footwear is required.
[if your riding partner stands their ground against any of these issues, take the car.]
