first off WELCOME to this big messy place!
there is an annual rally the 2nd? weekend of june nearby your hood, just SOUTHEAST of normal...
i refer to this as the SUBnormal rally at moraine view/leroy.
nice people, good time and food (but lousy water)
check it out!
you posed a VERY general "is it ok?" question.
with virtually NO background info, or certainly not much.
"is it ok" yes.
"is it NOT ok" yes.
depends on what OK means.
now (just guessing) IF the specific question behind "is it ok" was...
"what are the hazards or issues or consequences of running a generator INSIDE a passenger vehicle,
even with the tail gate and windows open?"...
the answers MIGHT be more detailed.
it would seem the persistent SMELL of gasoline and combustion would be a negative,
along with the need to disconnect and stabilize the genset EVERY time the tv is needed for shopping or bopping around.
there is obviously the possiblity of LEAKS (the gensets have a fuel tube on the bottom) which leads to the risk of...
even ADDING gasoline can be messy INSIDE a passenger vehicle.
---this list could be expanded INFINITELY by others...
all or NONE of which factors into the "OK" equation.
RAMPs are available to assist with loading/unloading,
and there are many posts/threads on using ramps, here is one...
there are many pictures of HOW folks wrestle the 3k units in the LONG threads comparing 2k, 3k and paralleled gensets...
one could also install a SLIDER TRAY in the back of the suv,
so that the unit could be ROLLED out for use and the tv interior LESS exposed.
the debate is UNending about how much juice is 'needed' and this is 1 of many threads that goes there...
ultimately owners decided how much juice is "ok" and how often replacing burned out appliances is "ok" and so on.
you might benefit from having the 3k mounted ON the stream, that is more OK in some ways and for some owners...
the location showed in post 2 above has worked well for this owner for a long time.
several other threads show creative ways/locations for mounting a 3k or 2x2k gensets...
which gets back to the 'which genset or combination is best for any given situation'...
loading/unloading 2000 sized units is easier and 2x2000 is MORE ok for powering the AC in virtually every case.
so perhaps IF you plan a LOT of use and don't wanna sort out loading with ramps or other options...
consider selling and trying 2x2000 this summer.
given a BIT more detail, u might wanna start a thread on HOW someone with a specific or general disabilities "gets it done" while rving...
here's a short one but NOT many solutions were posted...
i know many 'streamers with health issues or physical challenges that have really creative strategies or tweaks to the stream...
it would be nice to see a good thread devoted to those issues and solutions.
visit the 'genset/solar' subforum and scan/read some of the LONGER older threads.
there are LOTS of great posts and very detailed info which is VERY useful in those threads...
here are just 3 to get u rolling...
keep reading, keep thinking and find places to ask your UNanswered questions...
just don't expect the answers to anticipate EVERY personalized issue.
and with more background details shared, there is better potential for targeted answers.
