To most this will be overly obvious, but to the new folks out there, this might help shape your decsion in finding a trailer that is the right size for you.
Last night for laughs, while in the Bambi as I got it ready to take back home, I decided to measure the interior living space and compare it to what the specs say.
What I found is that a 19' Bambi has **approx** 15' 9" of interior space. But the specs have the '03 Bambi at a hair over 19'! True it is. Airstream like all other manufacs state the hitch to the bumper end. On the Bambi this equals about 3' of overall length I measured last night.
If the numbers follow, this would mean that a 22' unit has about 17' and a 25' unit about 22'. These are not exact numbers, your results may vary.
As you consider purchasing your coach, be it new or used, keep in mind that interior living space will be a bit less than the actual length of the coach.
I know this seems very basic to some, but as I took the readings last night, I was a bit taken back that the interior was only about 15' 9". I can't imagine what a 16' unit actually has in interior living space. Perhaps others beginning the process might consider this info before making a final selection.
