you asked whether the wave 3 or buddy heaters would work just as well. as most things in life, there are pros and cons. i always like to know as much as possible and camp awhile before i make decisions. i'm more likely to be satisfied with my choices this way. some of the things to consider:
1. the casita furnace, pros, reliable heat source when boondocking, already properly vented so you can keep windows/vents closed when in use. cons, uses your battery to function, so you'll be left high and dry out there if your battery goes dead and can't be recharged. noisy, my friend complained bitterly about hers when we boondocked together last year. uses quite a bit of propane, expensive initially., not sure how well it functions at altitude. 3 friends in utah this year could not get their furnaces to work but they worked at low elevations in tx before their trip. they had a very cold, miserable time of it.
2. wave 3, pros, reliable heat source, does NOT connect to your battery, so no drain on it whatsoever,silent operation, no noise, sips propane by comparison, cheaper, can be stored anywhere when not in use, saves space inside the trailer, is advertised to work at all elevations without issues, cons, must be used with proper ventilation per the instructions to avoid carbon monoxide poisoning.
i'd still advise on a new trailer to get the furnace, but on my used trailer, i'll probably do what a friend suggested over fish dinner last night. i'll warm the trailer with my generator and invest in a good sleeping bag when camped in cgs that have generator hours. then start the generator again when legally allowed. otherwise, when overnighting in a walmart or such, i'll run the generator all night. my camping style is not to sit in a remote cold boondock for days/weeks/months, so this method should work fine for my situation.if things change, i'll probably invest in the wave 3. many friends use it for many years and are very happy with it.
as for tires, i'll probably replace them with the same ones casita put on. they've served me very well since feb 2, 2014 and many many miles.
have fun deciding your options and travelling with your casita.
