one more thing to consider.
our 21T Komfort is an actual 23.5 feet overall
one of my many camping buddies just bought a nifty new "21 footer ".
on our annual 9 day joint campout he brought his new trailer .
his 21 looked longer than mine so we got out the tape rule .
his 21 was really 25.3 or so .
my 21T lists a 480 # tongue weight , a 4800# axle weight .
in actual practice with 50 gallons of water it is 980 # tongue weight and 5300# on the axles .
we carry the heaviest camping gear under our snugtop canopy . firewood , 3 gallon propane tank , 2 EZ-UP Quik-Shades ,an 60 quart cooler full of soda, etc.
with a lightweight SUV we would not have that option .
none of the suv's that fit into a short garage would be safe towing our "short" 21 footer .
