Mary -
I think attending the Sebring Scamp Camp is an excellent idea!

(
Francie and I will be there from Sunday night until Friday/Saturday.)
You will undoubtedly see all kinds of trailers and tow vehicles.
When pilots select an airplane to rent or own, they often consider the
"mission profile" (i.e. "How far will I be going?"; "How many passengers
will I be carrying?"; "What is the purpose of the flight; sightseeing or
cross country travel?"; "Do I have the skill and experience to fly in
the expected conditions?", etc.)
I think that the same kinds of questions could be applied to trailer+TV
selection (i.e. "How often will I go?"; "How far will I go?"; "How long
will I stay out on each trip?"; "Will 90% of my destinations have good
flush toilets and showers?"; "How many people will I need to sleep?";
"Will "gas mileage" be much of a factor in my decision to go or not?";
"If my intended tow vehicle also serves as an "everyday driver", what
is the HP/Torque/MPG and how big a vehicle do I want to drive and
park every day?" )
While I agree that it might be
nice to make the perfect decision the
first time, I don't believe that it is essential. I'm not sure that you
will ever truly know what trailer and options will suit you until you
have been out camping/traveling for a while?
After Sebring, I'd suggest making the best decision that you can,
purchasing something as quickly as seems reasonable to you, and
getting out and doing some camping/traveling.
Make some memories!
Considering that used FGRVs are scarce and the resale values are
fairly high, the penalty for a "less than perfect" decision is only the
effort and cost of the initial purchase price minus the expected resale
value. (
You might also consider the delta between purchase and
possible resale as "renting" the trailer from yourself?

)
While our 2011 Honda CRV was and still is a great everyday driver
and was at least "adequate" as a tow vehicle, I much prefer to tow
a trailer that weighs much less than my tow vehicles rated capacity.
That is why we recently replaced my older "work car" with a 2014
Ford
Escape 2.0L I4 Ecoboost with ~240hp and ~270 ft/lbs of torque.
(
If you are towing with a lighter vehicle and near the top of your
vehicles rated capacity, I would definitely consider adding brakes
to your trailer. IMHO- While most other options are about
convenience/comfort - trailer brakes are about safety.)
While some folks are apparently skilled and patient enough to tow
at (or above?) their tow vehicles rated capacity, I don't think that
option is for everyone.
Just for fun ... and food for thought, below is the rig that was parked
2 spaces away from us at the LBL (Land Between the Lakes)
rally.
Apparently, there was a whole group with similar rigs that made a
trek up to Alaska.
As always, these ideas and opinions may be worth about what you
paid for them ($0.00) and
YMMV.
Good luck with your decision(s)!
