that's like......"almost NEW" for a Bigfoot
.... the last of the 1500 series (second generation) ....how far away did you find it???
Sellers come in varying types..... there's ones that say: "Don't know much about RVs but everything seemed to work for me"....definetely a type you want to avoid.....but 2004 is so young that would't stop me but be careful....then there's the ones that don't know/understand how their RV works but have a PILE of receipts from a shop to show you they have kept on top of everything while they owned it.....better.....if you get lucky you'll hit on a seller for whom the RV was his main hobby and he knows it and it's systems inside out...this kind of owner will probably have made well built, thought out modifications......
if you get it for a "good price".....I'd just buy it without looking at much.....if the price seems "dear" to you I'd do a little digging....a common failure is the power center needing to be replaced...and figure on a new battery
if that's the case.....ask seller when's the last time the bearings were repacked / brakes
looked at.....open all closets, lockers, under kitchen with a flashlight to look for signs of past leaks
....same with all interior wall finishes around windows
you mentioned AC in a previous post....if the trailer is pre-wired for AC (in a 2004 I'd bet on that) you will probably find a 20A RED breaker on the fuse panel (my 97 has that....somebody replaced the AC with a Fantastic Fan before I got it...and where I live I can see why)
you also mentioned axle/tire replacements.....axles can be flipped to get the body (rear bumper) higher off the ground...below is a picture of mine with a flipped axle
and new, beefier springs (extra leaf)...same old tires
you don't say what you'll be towing it with....these trailers weigh 3500 lbs fully loaded for travel and have a lot of "windage" (big wide square frontal area).....a vehicle with a tow rating of 4500-5000 lbs will make for relaxed driving and climb any hills comfortably... (FLA is flat but still...
last thing...these trailers come out of the factory overweight on the left side (big honkin' fridge
, bathroom, black tank, water heater all on that side)...when you load it for travel think "light left, heavy right"
