New owner has has questions.
 

I posted on here earlier and decided to buy a 1993 hi-lo. It is model 2693br. I have a few questions because the previous owner was not sure:
1) how do you know when the hot water heater is full?
2) How do you know when the hot water pilot light is lit?
3) What kind of maintenance should I do to the lift system?
4) How do you "seal" the roof?
5) If you do not have wtaer hookup, how do you use the portable water system?

Any advice from you experienced people would be appreciated.

#'s 1 and 5. You stick a hose (White drinking water safe hose if you will be drinking the water) in the fresh water tank fill and leave iit there till it overflows, then cap it off. Then turn the water pump on in the trailer and open the furthest hot water tap from the water tank to purge air from the lines. Expect some spitting and splashing till a full stream comes out. One the water is coming out solid, the hot water heater is full.
#2 Is your water heater a DSI (lights via a switch?) or manual light? If it's a manual light, you will be able to see the pilot. I'll let someone who is more familiar with those explain the process.
#3 Under the trailer, grease the guide rod and spray WD40 on the cables. Use a dry lubricant or parrafin wax on the guide bars on the side of the trailer. If using a spray on dry lube, make sure it's clear as the dry graphite will look like black spray paint.

A 93 model water heater probably has to have the pilot light manually lite.

My '95 has a manual pilot light on the water heater and fridge and a peizoelectric on the furnace.
You really should go to the excellent reference library on this forum. I checked at the manuals for my appliances are there. The actual manual will give you the exact methods.

Thanks for all the tips. Everything works great so far. The only thing I have not gotten an answer from an experienced owner is what people recommend for sealing the roof. Any recommendations?

Depends on what type of a roof you have.

HELP.
how did you post a new thread.
but beyond that - I am looking to buy a 17 foot hi-low trailer and I can't find any specs on it - i need to know the weight of it.
Did you find any source for information on the Hi-Low trailers?

What year is it? You can find the brochures in the reference library. Look at the FAQ tab. Look at the FAQ tab. It tells you how to start a new thread. You should be able to start a new thread from the home page.
