Own the Aluma and love it.
Pro's
1. Light-weight, easy to move around by hand, not to mention tow.
2. Don't have to worry about paint fading, but you'll have to either live with oxidation or use aluminum cleaner to keep it shinny.
3. Our's came with Condor chocks which are great for holding the front end of the bikes.
Con's
1. Wife loves to load up more stuff in the truck than we ever would have if taking the bike.
2. Learn to laugh at the people who'll call you a trailer queen; who cares what they think anyway.
3. Another item to keep maintenance on for tags and tires.
Good luck.
Eric is right on the above.
I tried to talk Judy into a MC210 but she is stubborn.
I have a 7X14 Haulmark Lowhauler but love my Aluma.
I have the MC10 and it's the best trailer I have ever owned.
Tazmun just bought one and he loves his.
The 210 is just a 2 bike version of the 10.
Once you get wheel chocks on it Don loading is easy.
No tight quarters, it's a great trailer.
I towed the SERGC on the MC10 to Ribfest with the Platinum and the mileage went down 6/10's of a gallon.
Don you can't go wrong with the MC210. The Aluma line of trailers have a reputation as good as a Bushtec.
Good luck. Call me if you decide to buy one, there are some accessories that make it even better.
