I currently have a 7’ x 14’ with 5’ vee so 19’ long total Tandem axle is a little harder pull
But the extra room in the trailer is nice when travelling. Lots of space for two sleds and any extra crap you want to bring. Fuel cans, spare tires, tools, portable heater And room to preform some repairs
and as others have said the added headroom is a real bonus
