well, one thing to note for those out there that are doing builds or even modifying something already existing...DO YOUR RESEARCH!
not to get on a soapbox...but if i did, i would want to build the soapbox myself because if i ordered it off amazon, i'd probably fall thru it.
one thing that has immediately caught my attention is that by putting "RV" or "Marine" on an item, it automatically gets a minimum 50% markup placed on it. anyone who has owned a boat knows that a stainless screw at lowes is $1 and the same screw in a package that has "marine grade" on it will be $2. it gets even worse when moving up to items like pumps and blowers, even though the same item can be found elsewhere a good bit cheaper, so just because a RV site has an item, it doesnt mean it cant be found elsewhere. somethings are going to be unique, like a sliding step for a camper. that is going to be specific to RVs and you'll just have to bite it on items like that.
i've also noticed a distinct pattern where quality of most things have simultaneously dropped in the last five years. people doing reviews are talking about replacing a pump or blower that has lasted 20 years only to buy a new one that might go one to two years at best. fairly consistent reviews of quality dropping off at a rapid rate. i needed a water pump and immediately checked out the Sure-flo brand because i had great experience with them in the past. even the ones listed as the better series were getting some consistent flak in the reviews, so brand loyalty needs to be re-evaluated now.
amazon is getting a LOT of third party vendors that are really shady and apparently amazon isnt responsible for these people even though they are using the amazon platform. from reading reviews and complaints, it appears that a lot of the vendors on amazon that have the lower prices are ripping people off and amazon gives them a pass since amazon is still getting paid. a different subject, but the wife was looking a some kind of fancy skin cream and was telling me how she was reading a ton of complaints on how third party vendors are somehow taking the expensive bottles and putting regular hand lotion in it and selling it for $40 and amazon says they arent responsible for what third party vendors are doing...well, as long as amazon gets their cut of course. so yeah, really have to pay attention. back in the day, if i saw an item on amazon that i wanted, i just clicked and that was it. not anymore. i recently needed a milwaukee 18v battery and noticed one a lot cheaper than the others. it was a knock off. i looked at the seller and saw that it was some weird name like happyfuntime27 somewhere in china. the 5 star reviews were actually 2 reviews done in broken engrish which i would say were fake, but it still gave the item a 5 star rating when glancing at the product initially.
DECEPTION is the soup-de-jour when it comes to online ordering. (ha! i remember online dating was equally bad. meet a hot chick on Match and later go meet up at Waffle House in real person only to find out she has a peg leg and facial hair. and just because i went home with her didnt mean i wasnt disappointed...)
anyway, i guess just check reviews really close and who the actual vendor is and then cross check reviews on other platforms. it doesnt look like there are many great products out there anymore, but some will be better than others. and my biggest lesson learned is to make things easy to get to. if i had a pump that i knew would last 20 years, i would mount it in a hard to reach, out of the way place under the tank. well, i'm probably going to have to change items like that out now fairly often, so put them in an easy to access place.
