And in addition to the above I would recommend the idea that whatever you buy you may not keep very long. Not because the coach is "a problem" but because you and yours have a much
better idea of what size, floorplan and amenities are preferred with some experience.
Expect, for example that anything less than 15,000-btu A/C unit in a 23' or larger is really not up to Texas summer heat (especially if parked in sunlight). So
-- as with what follows -- there are immediate
trailer supplies and/or necessities that will come up with any coach bought.
Between now and trailer purchase, go ahead and order up a PRO-PRIDE hitch, a MAXBRAKE controller, and set aside enough for new axles (year dependent) and a disc brake retrofit
. See threads on LED running lights as well as LED brake/signal lights (buy once TT purchased). (Same for 7-way harness, safety chains and breakaway switch on older units).
Lynx Levelers, Rotochoks, Sewer Solution, etc. Dedicated torque wrench, highest quailty digital air gauge (tire pressure), etc. Pro quality fire extinguisher[s], CO, LP, Smoke alarms. Weather hazard radio.
Locate who in your town does trailer
alignments (maybe whom you have install the new axles if required) and, IMO, new coach batteries (brand, type,
size, cabling, etc).
Texas requires a safety inspection
(road safety) that a trailer service facility can do.
Everything you can do to cover the TT needs
for safe, legal compliance with new, better, brighter
as concerns on-the-road performance should be first on the list.
And a new set of LT-spec tires with CENTRAMATIC balancers.
IOW, some homework off to the side when trailer gazing
induces the thousand yard stare.
There are no end of well-done threads around here of which this is a good starter example
