I missed this thread when it was posted…agree you should go with tandem.
I probably would have bought a tandem in 2019 when I bought my new buggy and needed a wider one than the 1 year old Holmes 5’ x 10’ I had, but the same dealer gave me a deal I couldn’t refuse with trading it back to them.
I haul quite a bit of firewood through the summer on my Holmes 6’ 4” wide by 10’ long utility trailer. Also my Can Am Defender rides nicely on it.
