The thing with the nano is no tub surround.. deal breaker for me..
And single axle.. Cant carry C*ap
Umm the winnie.. small too IMO..
Your RT can pull 7400 lbs with a payload of 1300 lbs.
Who you putting in the truck? weight wise?
The trailers you speced out I dont think you can put more then 800 lbs in those..
I would lean towards this. I had one( 21fq) and it carried nearly 3000 lbs. Not that you can fit 3000 lbs in there but you will thanks me later..
This would be something you can keep a while and youll be comfortable.
Its light enough IMO
