First Rally, what to take/expect
Greetings Stephanie!
The following is a list of the "basic" supplies that I have in my rally preparedness kit:
1. Leveling blocks sufficient to raise the low side of the coach up to 2.5" - - a set of wheel chocks will also be necessary for front and rear of each tire since your coach is a single axle.
2. A wide-footed tongue jack base as well as large, flat block of wood to place under the tongue jack base.
3. A 30-AMP to 15-AMP electrical adapter. (I also carry 75-feet of 30-AMP extension cord, but I will readily admit that this is overkill.)
4. Free-flowing (non-restricted) <doesn't have shut off vlaves> "Y" for your water supply (a metal Y is best as the plastic ones seem to be good for only one or two rallys before they spring leaks), and at least 50 ft. of white RV (potable water approved) hose. You might also find it helpful to have a 3' to 5' potable water hose to run from your trailer's city water inlet to the "Y" as this will reduce the potential of over-stressing the plumbing connection on the coach. (My usual rally supply includes 3-75 foot lengths of the hose as I always seem to be the first in the row so must reach to the hydrant.) {Since this is your first rally, this may see strange but at many rallys the water supply is "daisy-chained" from one main hydrant to any number of trailers in a row - - the first trailer connects to the hydrant with the next connecting to the first trailer's "Y" . . . . and so-on to the end of the chain. An additional consideration is being prepared if you happen to be the last person in the chain (either permanently or temporarily) - - then you will need a "cap" for one side of your "Y".}
5. A mat for in front of your entrance door [a 3' x 5' is probably about the minumum for good protection]. {I have a patio mat that is sold at most larger Rallys that is really nice for the purpose - - it is in excess of 9' x 12' and is made of a breathable fiber that doesn't kill the underlying sod.}
6. Provisions for gray water (wash water)
a. Blue tank for those locations where gray water must be properly disposed of.
b. Thetford Cap for dump valve with hose outlet.
c. 4' black "automatic washer supply hose" to run between Thetford cap and blue tank - - or to route under rear of coach where it is permissible to allow wash water onto the ground.
7. Flags and flag holder for front of coach. (I usually carry US Flag, Canadian Flag (for Canada Day at International Rally), VAC flag, and my state flag).
8. A Citizen Band radio is often valuable at larger Rallys as this is the way announcements are often made. A battery operated, hand-held portable will work - - just be prepared with an extra set of batteries - - it is also helpful if you happen to participate in a "Suburban Caravan" to a site or eatery as the leader communicates with the followers via the CB.
9. Be sure that your propane tanks are full, your water tank is full, and that your black tank is empty when arriving at the rally as the water supply may not be immediately available, and a dump site may not be conveniently located either.
10. Extra fuses for both 12-volt and AC fuse box (if so equipped).
11. A temporary shut-off valve to mount between your "Y" and your trailer on the water supply hose so that if you happen to spring a leak you can shut down the supply to your trailer quickly without interrupting the supply to the rest of the chain.
Depending upon the Rally, you might also want to be prepared for several other possibilities.
A.) A pot-luck is a function at many rallys so it is wise to be prepared with a pot luck idea {mine is bon-fire baked beans made in a dutch oven that can be made over a bar-b-que grill using canned goods that are easily carried in either the tow vehicle or trailer}.
B.) Semi-formal activities. There are any number of semi-formal activities at a number of rallys including such things as ballroom dancing, line dancing, or square dancing. These are typically dress-up ocassions, but not necessarily the full formal route - - I usually pack a dress shirt, dress slacks, and a bolo tie for such ocassions.
C.) Vintage Club Open House. Since yours is a vintage coach, if there is a Vintage Club section at the Rally you will likely be invited to participate in the open house (if one will be part of the Rally). The open house is a fun time where owners open their trailers for a period of one to two hours for visitors to tour the coach - - it is a time when much visiting occurs, and much sharing takes place. Be prepared for lots of questions and any number of interesting conversations.
You are correct about the folding chairs. In addition, it is usually wise to be prepared for any weather condition that might prevail (I usually carry an extra sweater, wind breaker and stadium blanket for the "campfire" activities that are often an impromp-tu part of a rally)as well as being prepared for any pesky insects that might make their presence known.
With best wishes for a turly memorable and enjoyable experience at your first Rally!
Kevin
