With those tanks, just make sure the axle and tires can handle it.
Don't want a bent axle or to go through tires every 6 months.
And as I'm sure you are aware already, check the tongue weight to make sure its between 10-15%.

Your solution of SH will be approx. 9 pounds per gallon.
Your water is 8 pounds per gallon.

I won't run an axle under 2500 pound rated even on a small rig.

Well I would wire your battery to your tail light hook up (get a 6 way) to charge it while you are out running  from job to job , also how close is the pump  to  the battery,the pump look like its a good ways from the battery , fat boys like everything big and the battery needs to be placed by the pump... Mike Sullivan I think explains this in another thread,
could cause wires to heat up and will loose amperage blow fuses...
nice little trailer great build my friend



Dave

I got the trailer built with a 3,500 lb axil.  The large tank cage sits slightly to the rear which helps to displace the toung weight.  Ordered the trailer with 15" tires....Thanks for your response, I appreciate the input.

I have a 7' run from the battery to the pump.  Ran 10 gauge copper wire.  No blown fuses yet.  Thanks for the info.  will keep 6 way in mind.

The SH is 10lbs per gallon, not 9 very important. Every one of those exposed bolts needs a coating of teflon nevercease and silicone. It will only take about 2 months for them to rust solid. I really like the barrel holders you added. A rubber mat would save the deck, the thin nylon straps will last about one season. For what you built, I would say you can use and abuse that rig for 2 seasons cleaning daily. After that it will be very rusty and the wood will be shot. This is a good!! If you are cleaning daily you will make plenty of money and have plenty of concept for your next one.

Very clean and organized - clients appreciate a well tended rig. We've gotten extra jobs just from that. Letter helps too, of course!

I thought I read somewhere it was 9.42 pounds per gallon but now I can't find that article.

Can you remember where you got the 10 per gallon?

This time I'll write it down, lol

I have to give credit to my brother in law for the welding, he is an Engineer with a complete metal fabrication shop.  I paid $900 for the trailer.  Trailer had pressure treated flooring, I had them increase the axle weight from 2,200 lbs. to 3,500 lbs, incresed the tire size to 15' and also got a spare tire (welded spare tire mount to bottom of trailer just behind tongue area).  Bought pump, keri tech hose (200' 3/4"), conectors, nozzels, wand, mis. hoses, filters, cam-lock etc. from PWP. Got 250 gal. tank with cage from Brother in laws contcts at no charge,  paid on av. $10 for 55 gal. tanks off craigs list.  Tool box was dented got it half price at $75. Misc. steel, nuts & bolts, deck screws cost about $200.  Marine battery 875 cranking amps from Wal-Mart $95.  I would say total out of pocket I spent about $2,500.  The additional costs were the time spent in travel, phone time getting the correct items and last but not least the fabrication time of 40+ hours ( haven't recieved brother-in-law's bill yet...LOL).
