One major advantage of a shorter trailer is the manueverability it offers in tighter turns .
There are more active posters on this forum that prefer the longer trailers .
After having a 36' diesel pusher and a 26 foot TT I decided to order a new Komfort 21T a decade ago . The TT is 23.5 feet with the tongue .
With my diesel extracab short box gmc I can manuever into most any station when towing .
I am from the school that says the shortest trailer that fits my needs rather than the longest works best .
My 21T has 1 potty , 1 bathtub , 1 6cu ft refer , 6 gallons water heater , a double kitchen sink , 1 oven , 2 big propane tanks , 2 batteries , 50 gallons fresh , 45 grey, and 45 black just the same as the 27 footer ( 29' actual ).
Going down the road I am definitely more stable than my longer friends .
I have less uncontrolled weight on the Lever that is behind the trailer axles.
And I can get into any station and many campsites that the longer rig cannot use .
